Cov chav khaws thiab faib tshuaj hauv chav huv feem ntau nyob hauv thaj chaw tsim khoom pabcuam, feem ntau nyob rau hauv pem teb hauv av ntawm lub tsev ib txheej lossis ntau txheej, ze ntawm phab ntsa sab nraud. Cov tshuaj yuav tsum khaws cia sib cais raws li lawv cov khoom siv lub cev thiab tshuaj. Cov tshuaj tsis sib xws yuav tsum muab tso rau hauv cov chav khaws thiab faib tshuaj sib cais, sib cais los ntawm cov khoom sib cais. Cov tshuaj txaus ntshai yuav tsum khaws cia rau hauv cov chav khaws lossis faib tshuaj sib cais nrog qhov ntsuas tiv taus hluav taws tsawg kawg yog 2.0 teev ntawm cov chav sib ze. Cov chav no yuav tsum nyob hauv chav ntawm thawj pem teb ntawm lub tsev tsim khoom, ze ntawm phab ntsa sab nraud.
2. Cov chav huv hauv kev lag luam hluav taws xob feem ntau muaj cov chav khaws cia thiab faib cov kua qaub thiab alkalis, nrog rau cov kuab tshuaj uas yooj yim hlawv. Cov chav khaws cia thiab faib cov kua qaub feem ntau muaj cov tshuab khaws cia thiab faib cov kua qaub sulfuric, phosphoric acid, hydrofluoric acid, thiab hydrochloric acid. Cov chav khaws cia thiab faib cov kua qaub feem ntau muaj cov tshuab khaws cia thiab faib cov kua qaub sodium hydroxide, hydroxide cake, ammonium hydroxide, thiab tetramethylammonium hydroxide. Cov chav khaws cia thiab faib cov kuab tshuaj uas yooj yim hlawv feem ntau muaj cov tshuab khaws cia thiab faib cov kuab tshuaj organic xws li isopropyl cawv (IPA). Cov chav huv hauv cov nroj tsuag tsim cov khoom siv wafer kuj muaj cov chav khaws cia thiab faib cov tshuaj polishing slurry. Cov chav khaws cia thiab faib cov tshuaj feem ntau nyob hauv cov chaw tsim khoom pabcuam lossis cov chaw txhawb nqa ze lossis nyob ib sab ntawm cov chaw tsim khoom huv, feem ntau nyob rau hauv pem teb thib ib nrog kev nkag mus rau sab nraum zoov.
3. Cov chav khaws tshuaj thiab faib tshuaj muaj cov thoob ntim tshuaj lossis cov thoob uas muaj peev xwm sib txawv raws li hom, ntau npaum li cas, thiab cov yam ntxwv siv ntawm cov tshuaj uas xav tau rau kev tsim khoom. Raws li cov qauv thiab cov cai, cov tshuaj yuav tsum khaws cia cais thiab faib ua pawg. Lub peev xwm ntawm cov thoob lossis cov thoob uas siv yuav tsum txaus rau xya hnub siv cov tshuaj. Cov thoob lossis cov thoob txhua hnub kuj yuav tsum muaj, nrog lub peev xwm txaus los npog 24-teev siv cov tshuaj uas xav tau rau kev tsim khoom. Cov chav khaws khoom thiab faib cov tshuaj yaj uas yooj yim hlawv thiab cov tshuaj oxidizing yuav tsum sib cais thiab sib cais los ntawm cov chav sib ze los ntawm cov phab ntsa ruaj khov uas tiv taus hluav taws nrog qhov ntsuas tiv taus hluav taws ntawm 3.0 teev. Yog tias nyob rau hauv pem teb thawj zaug ntawm lub tsev ntau txheej, lawv yuav tsum sib cais los ntawm lwm qhov chaw los ntawm cov plag tsev uas tsis kub hnyiab nrog qhov ntsuas tiv taus hluav taws tsawg kawg yog 1.5 teev. Chav tswj hwm hauv nruab nrab rau kev nyab xeeb tshuaj thiab kev saib xyuas hauv chav huv yuav tsum nyob hauv chav sib cais.
4. Qhov siab ntawm cov chav khaws tshuaj thiab faib tshuaj hauv chav huv yuav tsum txiav txim siab raws li cov khoom siv thiab cov kav dej uas yuav tsum tau teeb tsa thiab feem ntau yuav tsum tsis pub tsawg dua 4.5 meters. Yog tias nyob hauv thaj chaw tsim khoom ntawm chav huv, qhov siab ntawm chav khaws tshuaj thiab faib tshuaj yuav tsum sib xws nrog qhov siab ntawm lub tsev.
