Граніт – що це за порода каменю, характеристики, склад, застосування

Автор: Алина Веденеева 18.01.2023


Граніт – природний камінь магматичного походження з унікальними фізико-механічними характеристиками. Матеріал має високу міцність і унікальні естетичні характеристики, тому вважається уособленням стилю і довговічності. Він широко використовується в будівництві, зовнішньому облицюванні будівель, інтер'єрних декоративно-оздоблювальних роботах.

Походження

Гранітні родовища, що залягають під осадовими породами, сформувалися на стику тектонічних плит. Розплавлена магма під тиском піднімалася через тріщини в земній корі, поступово остигаючи і перетворюючись на скам'янілі структури.

Існує альтернативна версія утворення гранітних покладів внаслідок процесу гранітизації (кристалізації). Відповідно до цієї теорії осадові гірські породи через тектонічний зсув опускалися під землю на глибину 10-15 км, де під дією колосальних температур і тиск переплавлялися, утворюючи гранітну породу. Потім на деяких ділянках процеси ерозії, опади та вивітрювання зменшили глибину залягання пластів до кількох метрів, прийнятну для видобутку.

Поклади граніту зустрічаються всіх континентах. Це друга за поширеністю порода земної кори після базальту, тож граніт часто називають «візитною карткою» нашої планети. На території Росії налічується близько 50 найбільших родовищ, які розташовані в основному в Східному Сибіру, Карело-Кольському регіоні, на Уралі, Далекому Сході.

Хімічний та структурний склад


Гранітна порода є комбінацією трьох основних речовин у різних пропорціях:

польовий шпат (луги та кремнієві кислоти) — 60-65%;
кварц - 25-35%;
слюди (біотит) – 5-10%.
Від кількості польового шпату залежить колір екземпляра. Відсоткове співвідношення кварцу визначає ступінь напівпрозорості зерна. Чим вище вміст біотиту, тим більше виражені переливи за зміни кута зору. Також порода містить включення заліза, алюмінію, кремнію, магнію, кальцію.

Методи видобутку
Найчастіше граніт видобувають недорогим та простим вибуховим методом. По периметру ділянки пробурюють отвори та закладають у них вибухівку. Шматки, що відкололися після вибуху, сортують, нарізають на блоки і відправляють на завод для подальшої переробки. Основний недолік технології – великий відсоток відходу. Близько 30% породи після вибуху розколюється на дрібні, не придатні виготовлення виробів фрагменти, які вирушають на переробку в гравій. Крім того, вибухова хвиля негативно впливає на структуру та міцність матеріалу.

Видобуток за технологією повітряної подушки - щадний, але дорожчий і витратний за часом спосіб. У поглиблення по межах ділянки, що розробляється, закачують повітря, створюючи таким чином високий тиск, під впливом якого брили відколюються від загального масиву.

Використання каменерізів, спеціального обладнання з алмазними насадками, - найдорожчий і практично безвідходний спосіб розробки, що дозволяє отримати гранітні брили правильної форми без пошкоджень.

Види обробки

На завод https://b-granum.com/uk/ граніт надходить у вигляді блоків розміром 3*1,5 м масою близько 20 т, які розрізають на слеби, а потім обробляють одним із способів:

Шліфування та лощення. Обробляє абразивні алмазні круги різної фракції, в результаті чого виходить гладка матова поверхня. У процесі шліфування з поверхні видаляють мікротріщини, отримуючи абсолютно гладку поверхню із закритими порами, в які не проникає вода.
Полірування. Операція, яка дозволяє виявити красу каменю, надати характерного дзеркального блиску і створити виражену глибину кольору.
Випалювання полум'ям газового пальника - вигляд грубої обробки. Під впливом високої температури кварц, що міститься в граніті, вибухає, внаслідок чого утворюється поверхня із шорсткою фактурою.
Бучардування. Обробка попередньо відполірованої поверхні на шліфувальній машині з барабанами з метою отримання шорсткої поверхні. Використовується для створення протислизьких сходів та підлогових покриттів.
Після оздоблення плити розрізають на деталі потрібних розмірів, надають певної форми залежно від призначення майбутніх виробів.

Властивості граніту

Граніт — один і найміцніший, твердіший і стійкіший до природних впливів каменів. Він морозостійкий, пожежобезпечний, не боїться коливань температур і вологості, не схильний до ураження грибками та пліснявою. Водопроникність необробленого матеріалу мізерна мала, а після обробки він стає практично непроникним для вологи.

Граніт, як і будь-який інший природний камінь, має деяку радіоактивність, але для застосування всередині приміщень використовуються види з найнижчими, безпечними для людини показниками.

As a widespread rule, NBA 2K defenses over assist, specifically off the nook shooters. This is going along side rule one to a few degree, however both manner defenses nevertheless slide too a ways off their protective assignments at factors. You can not surrender a ton of open nook 3s withinside the NBA, and also you surrender plenty of them in NBA 2K23 MT until you definitely micro-control matters.three. You ought to extra effortlessly be capable of installation widespread protective standards. The "factors of emphasis" of pronouncing "restrict perimeter photographs" isn't always useful on its very own because it simply results in every body being blanketed tightly on the fringe.

This results in plenty of backdoor cuts and so on (which is a great factor). You can set character assignments — like "deny" and "tight" — however can best do that after coming into an real sport.In franchise mode (on line and stale), those principles ought to be elevated upon so that you can scheme such things as "do not assist off shooters in nook" or some thing else alongside the ones traces.

Alternatively, simply permit customers to have all of the menus we've got in-sport made to be had to be used earlier than video games.Okay, now permit's get to the GIFs:Semi-Transition Offense Is MoneyNBA coaches pontificate and pontificate approximately getting stops, securing the rebound and getting out at the ruin. In component, they speak approximately this loads due to the fact even semi-transition may be tough to cope with, specifically whilst groups are pass matching. This is likewise a massive motive why offensive rebounding has been de-emphasised through the years; groups are involved approximately getting returned on protection first and fundamental.

In the instance above, you notice Steph Curry beat in semi-transition as he attempts to select up the ball handler nicely above the three-factor line.

However, you do not definitely see any defenders step up.Instead, you land up with 3 gamers beneathneath the ring all looking forward to the ball handler. This results in a skip into the nook for a huge open jumper. In quick, no one definitely takes movement in a manner that facilitates, which results in the ball handler having a unfastened run on the hoop to make a play.

In a super international, the massive steps up, and the wing denies the skip to the nook whilst Curry recovers and receives returned withinside the play.Here's a comparable NBA instance:In this instance, Curry is truely quite nicely contained with the aid of using Avery Bradley, and Jared Sullinger is there to assist due to the fact Bogut is trailing the play. Evan Turner is one skip away, however he makes the error of taking too many steps toward the paint, and this lets in Curry to make an clean skip to Harrison Barnes for the open jumper. Turner is the best participant at fault right here.This differs from the NBA 2K play in that one participant (Turner) makes a small mistake, however the different gamers do their process.

If Bradley have been burned, not anything could have modified as Sullinger nevertheless could had been there, and Turner's mission nevertheless could had been Barnes withinside the nook. In the 2K instance, one participant stepping up nevertheless approach different gamers had been nevertheless arguably out of role.Here's one extra instance from NBA 2K:Again, the problem is lots of gamers grow to be in no guy's land. The on-ball defender receives burned at the preliminary movement, however the offensive participant at the wing is huge open as quickly as this takes vicinity.

You have as a minimum gamers at the Warriors sitting withinside the paint now no longer definitely guarding anybody or supporting at the force.I'm highlighting this to definitely display off the reality that semi-transition ought to be powerful, however it should not always be that first skip that absolutely ruins your protection Buy NBA 2K MT. Or to place it any other manner, simply due to the fact an on-ball defender receives beat does now no longer imply a person ought to at once be huge open whilst all 5 gamers have tracked returned on protection.The Skip Pass Is DeadlyHere's a place wherein I truely need to guard NBA 2K.
