Txhawm rau tiv thaiv cov thawv yas los ua pa nkev, qhov kub ntawm qhov siab thiab lub taub hau yog qhov qis thiab yuav tsum tau kho. Yog hais tias cov khoom yooj yim degraded, qhov kub ntawm lub chim thiab nozzle yuav tsum tau tshaj. Txo cov txheej txheem rov qab thiab ceev ceev ntawm cov ntsia hlau ua rau cov khoom siv me ntsis xoob thiab txo qhov degradation ntawm cov yas vim yog overheating. Cov pwm kub yog siab dhau heev lawm thiab nws tsis yooj yim. Cov pwm kub yog tsawg dhau, cov yas yog prematurely txias, lub fusion sib txuas yog tsis zoo fused, thiab tawg yog yooj yim, tshwj xeeb tshaj yog rau high melting point plastics xws li polycarbonate. Tus cag kab noj hniav yuav tsum muaj ib txoj kab lus zoo. Thaum tus tub ntxhais kawm nyuab nyuab heev, nws tsim nyog ua ntej kom sov qhov kub thiab qhov kub txias. Thaum cov kab noj hniav yooj yim tshem tawm, nws tsim nyog kom txo cov kab noj hniav kom ntev thiab ntev rau lub sij hawm txias.
Cov thawv yas tsim kev xav txog kev lag luam: kaw haujlwm, kho kom zoo dua. Nws yog qhov tsim nyog rau tus neeg teb xov tooj kom tau txais kev kawm tshwj xeeb los ua raws nraim li cov txheej txheem khiav hauj lwm. Ua raws li tus neeg teb xov tooj uas siv lub tshuab npog npog yus tus kheej (lub npog ntsej muag ib nrab), hnav tshuaj thaiv kev tiv thaiv, hnav khaub ncaws hnav, hnav cov hnab looj tes roj hmab thiab roj. Txav deb ntawm hluav taws, kub, thiab haus luam yeeb hauv chaw ua haujlwm. Siv qhov cua tshuab qhov cua tshuab thiab cov cuab yeej siv. Tsis tas li ntawd, lub chaw tsim tshuaj tua kab tsis tiv thaiv kom tsis txhob mus rau hauv qhov chaw ua haujlwm hauv huab cua. Tiv thaiv kev tiv thaiv nrog oxidants, acids, thiab halogens. Thaum sau cov thooj av fais fab, qhov ntsuas yuav tsum tau tswj thiab ib qho av ntaus khoom yuav tsum muab nruab rau kom tiv thaiv tau hluav taws xob hauv hluav taws xob. Maj mam ntim thiab thau khoom thaum lub sij hawm hloov mus rau kev tiv thaiv kev puas tsuaj rau ntim thiab ntim. Txhawb nqa nrog cov khoom sib txuas thiab ntau ntau ntawm cov khoom siv tua hluav taws thiab cov khoom siv thaum muaj xwm txheej ceev rau kev xau. Cov thawv ntim yuav muaj cov khoom uas tsim kev puas tsuaj.
Cov yam ntxwv nta: cov yas mos mos, lub cev nyhav, lub zog zoo, kev ua haujlwm, kev ua haujlwm tsis zoo, quav, tsis muaj tshuaj lom thiab tsis qab, yooj yim rau kev thauj. Cov khoom tsim rau txhua yam ntawm cov zaub mov kua ntsev, seasonings, cov tshuaj thiab cov khoom siv kho mob, cawv Thiab cov khoom ntim tshuaj, cov khoom ntim: acid, alkali, high temperature, non-toxic, sterile, tasteless, thiab muaj zoo tiv thaiv ncab thiab cuam tshuam ; folding stacking cia, hnyav, kaus poom, tag nrho Cov txheej txheem zoo heev txuag chaw thiab txuag cov ntaub ntawv. Lub teeb yuag, txias tsis kam, corrosion kuj, txo qaug qis, super huv, thiab ua tau raws li cov kev cai ntawm kev kuaj mob.
