Cov pwm yas puas tuaj yeem siv los ua cov khoom sib txawv?

Cov txheej txheem txheej txheem ntawm cov khob dej yas feem ntau yog txhaj tshuaj molding thiab tshuab molding. Cov txheej txheem tshuab moulding tseem hu ua lub raj mis tshuab txheej txheem. Vim muaj ntau yam ntaub ntawv yas los uakhob dej, muaj AS, PS, PP, PC, ABS, PPSU, TRITAN, thiab lwm yam. Thaum tswj cov nqi, ntau lub tuam txhab thiab cov neeg siv khoom khob dej txhua tus xav txog seb lawv puas tuaj yeem siv tib lub pwm los ua cov khoom siv yas. Qhov no puas ua tau? Yog tias nws tuaj yeem ua tiav, cov khoom tiav puas yuav muaj txiaj ntsig zoo ib yam?

Yog li cia peb tham txog nws cais. Hauv cov txheej txheem txhaj tshuaj molding, cov khoom siv feem ntau yog AS, ABS, PP, thiab TRITAN. Raws li cov yam ntxwv ntawm cov khoom siv thiab cov kev hloov pauv uas tshwm sim thaum lub sijhawm tsim khoom, AS thiab ABS tuaj yeem sib koom ua ke hauv tib lub pwm, tab sis PP thiab TRITAN tsis tuaj yeem sib koom tib lub pwm thaum txhaj tshuaj molding. Tib lub sijhawm, cov pwm tuaj yeem sib koom nrog AS thiab ABS. Cov nqi shrinkage ntawm cov ntaub ntawv no txawv, tshwj xeeb tshaj yog qhov siab shrinkage tus nqi ntawm cov ntaub ntawv PP. Ua ke nrog cov txheej txheem ntawm kev txhaj tshuaj molding txheej txheem, cov ntaub ntawv yas tsis tshua muaj pwm sib koom.

Hauv cov txheej txheem tshuab raj, AS thiab PC ntau lawm tuaj yeem faib cov pwm, thiab cov khoom tsim muaj kev ua haujlwm zoo sib xws. Txawm li cas los xij, PPSU thiab TRITAN tsis tuaj yeem sib koom pwm vim tias ob qho khoom sib txawv heev. PPSU yuav zoo li mos rau lwm yam khoom siv, yog li tib lub raj mis tshuab pwm tsis tuaj yeem siv rau PPSU cov ntaub ntawv thaum nws siv nrog AS cov khoom. siv. TRITAN cov khoom yog ib qho nyuaj piv rau lwm cov ntaub ntawv. Tib yam yog vim li cas. Pwm tsim rau lub raj mis tshuab ntawm lwm cov ntaub ntawv tsis haum rau nws.

Txawm li cas los xij, txhawm rau txuag cov nqi, kuj tseem muaj lub khob khob dej uas sib koom lub raj mis tshuab pwm rau AS, PC, thiab TRITAN, tab sis cov khoom tsim tawm yog qhov tsis txaus ntseeg. Qhov no yuav tsis raug ntsuas.
