Cov ntoo hluav taws xob thiab cov khoom ntoo yog cov khoom siv sib xws, tab sis lawv cov nqi sib txawv heev. Feem ntau, tus nqi ntawm cov ntoo hluav taws xob tuaj yeem ncav cuag ntau zaus ntawm cov khoom ntoo. Vim li cas qhov xwm txheej no tshwm sim? Kab lus no yuav tshawb txog qhov cuam tshuam ntawm cov nqi ntoo hluav taws xob los ntawm ntau qhov kev xav thiab txheeb xyuas lawv cov laj thawj.
1. Cov nqi raw khoom
Cov ntoo hluav taws xob yog cov yas thermosetting ua los ntawm polymerization ntawm phenolic tebchaw thiab formaldehyde, thaum cov ntoo ua tiav los ntawm cov ntoo ntuj. Tus nqi ntawm phenolic tebchaw thiab formaldehyde kuj yog siab, thiab cov kev cai rau synthesis tshuaj tiv thaiv tej yam kev mob kuj nruj, uas ua rau siab raw khoom nqi rau hluav taws xob ntoo. Hauv qhov sib piv, tus nqi raw khoom ntawm cov khoom ntoo yog qhov tsawg vim tias tus nqi ntawm cov ntoo ntuj yog qhov ruaj khov thiab cov txheej txheem ua tau yooj yim.
2. Tus nqi tsim khoom
Cov txheej txheem ntawm cov ntoo hluav taws xob yuav tsum muaj ntau yam txheej txheem thiab kev ua haujlwm nyuaj, suav nrog kev npaj cov khoom siv raw, cov tshuaj tiv thaiv synthesis, molding, kev kho cua sov, thiab lwm yam. Cov txheej txheem no yuav tsum muaj cov cuab yeej siv siab thiab thev naus laus zis, thiab muaj kev ua haujlwm siab, uas ua rau cov nqi ntau lawm rau hluav taws xob ntoo. Hauv qhov sib piv, kev ua cov khoom ntoo yog qhov yooj yim, tsuas yog xav tau sawing, polishing, pleev xim thiab lwm yam txheej txheem, uas ua rau cov nqi qis dua.
3. Kev ua tau zoo
Cov ntoo hluav taws xob muaj ntau yam kev ua tau zoo, xws li thermal stability, zoo rwb thaiv tsev, zoo hnav tsis kam, thiab yooj yim ntawm kev ua. Cov kev ua tau zoo no ua rau cov ntoo hluav taws xob hloov tsis tau hauv ntau qhov chaw. Hauv qhov sib piv, kev ua tau zoo ntawm cov ntoo yog txwv los ntawm cov khoom siv ntuj tsim, xws li susceptibility to noo noo thiab deformation, uas txwv nws daim ntawv thov hauv qee qhov chaw. Vim qhov zoo ntawm kev ua tau zoo ntawm cov ntoo hluav taws xob, cov neeg txaus siab them tus nqi siab dua los yuav cov khoom siv hluav taws xob hauv ntau qhov xwm txheej.
4. Kev lag luam khoom thiab kev xav tau kev sib raug zoo
Kev lag luam kev lag luam thiab kev xav tau kev sib raug zoo yog ib qho tseem ceeb cuam tshuam rau cov nqi khoom muag. Qee qhov xwm txheej, vim qhov kev thov siab rau cov ntoo hluav taws xob hauv kev ua lag luam thiab cov khoom siv qis, cov nqi hluav taws xob tau nce. Nyob rau hauv sib piv, cov khoom lag luam thiab kev thov kev sib raug zoo ntawm cov khoom ntoo yog qhov ruaj khov, yog li tus nqi kuj tseem ruaj khov. Kev hloov pauv hauv kev lag luam thiab kev thov tuaj yeem ua rau muaj kev hloov pauv ntawm cov nqi hluav taws xob thiab cov khoom ntoo.
