Yuav ua li cas tswj cov xim sib txawv ntawm kev txhaj tshuaj molding tshuab khoom?

1, Tshem tawm qhov cuam tshuam ntawm kev txhaj tshuaj molding tshuab thiab cov pwm pwm
Xaiv lub tshuab txhaj tshuaj molding nrog tib lub peev xwm raws li cov khoom siv tshuaj molding thawj. Yog tias lub tshuab txhaj tshuaj molding ntsib teeb meem xws li cov ntaub ntawv tuag cov ces kaum, nws yog qhov zoo dua los hloov cov khoom siv. Cov xim sib txawv tshwm sim los ntawm lub rooj vag kaw lus thiab cov pwm tso tawm tuaj yeem daws tau los ntawm kev kho cov pwm ntawm qhov sib thooj ntawm cov pwm; Ua ntej npaj ntau lawm, nws yog ib qho tsim nyog los daws cov teeb meem ntawm kev txhaj tshuaj molding tshuab thiab pwm kom txo tau qhov nyuaj ntawm qhov teeb meem.
2, Txo qhov cuam tshuam ntawm kev txhaj tshuaj molding txheej txheem hloov kho
Thaum kho cov txheej txheem kev txhaj tshuaj molding tsis yog vim tsis muaj xim sib txawv, sim tsis txhob hloov qhov kev txhaj tshuaj kub, rov qab siab, lub voj voog txhaj tshuaj, thiab cov tshuaj masterbatch kom ntau li ntau tau. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los saib xyuas qhov cuam tshuam ntawm cov kev hloov pauv hauv cov txheej txheem ntawm cov xim; Yog tias pom qhov sib txawv xim, nws yuav tsum tau hloov kho raws sijhawm.
Sim tsis txhob siv cov txheej txheem txhaj tshuaj molding nrog kev txhaj tshuaj siab ceev thiab siab rov qab los ua kom muaj zog shear cuam tshuam, thiab tiv thaiv lub zos overheating lossis thermal decomposition los tsim cov xim sib txawv. Ua tib zoo tswj qhov kub ntawm txhua qhov cua sov ntawm lub thoob, tshwj xeeb tshaj yog qhov kub thiab txias ntawm lub nozzle thiab cua sov qhov ze ntawm lub nozzle.
3, Qhov cuam tshuam ntawm kev txo qis kub ntawm cov xim sib txawv
Nyob rau hauv ntau lawm, nws yog feem ntau ntsib hais tias vim kev puas tsuaj los yog tsis ua hauj lwm ntawm lub cua sov nplhaib los yog uncontrolled burning ntawm cua sov tswj Cheebtsam rau lub sij hawm ntev, qhov kub ntawm cov khoom chim hloov sharply, ua rau cov xim sib txawv. Cov xim sib txawv tshwm sim los ntawm qhov laj thawj no yooj yim rau kev paub qhov txawv; Feem ntau hais lus, qhov sib txawv ntawm cov xim uas tshwm sim los ntawm kev puas tsuaj thiab tsis ua haujlwm ntawm lub nplhaib cua sov yuav ua nrog cov yas tsis sib xws.
Txhaj tshuaj molding tshuab hom
Txawm li cas los xij, qhov kev tswj xyuas cua sov uas tsis muaj kev tswj xyuas thaum lub sij hawm ntev incineration feem ntau nrog cov pa roj, discoloration loj, thiab txawm cov khoom coking. Yog li ntawd, thaum lub sijhawm tsim khoom, cov khoom cua sov yuav tsum tau kuaj xyuas ntau zaus. Yog tias cov khoom cua sov puas lossis tsis muaj kev tswj hwm, nws yuav tsum tau hloov thiab kho kom raws sijhawm kom txo tau qhov tshwm sim ntawm qhov sib txawv ntawm cov xim no.
4, Tshem tawm qhov cuam tshuam ntawm raw khoom resins thiab masterbatches
Kev tswj hwm ntawm cov khoom siv raw yog tus yuam sij rau kev daws cov xim sib txawv, yog li ntawd, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov khoom siv xim xim, qhov tseem ceeb ntawm qhov sib txawv thermal stability ntawm cov ntaub ntawv resin ntawm cov khoom xim hloov tsis tuaj yeem tsis quav ntsej. Muab hais tias feem ntau cov tuam txhab txhaj tshuaj molding tsis tsim cov yas masterbatches lossis xim masterbatches, lawv tuaj yeem xyuam xim rau kev tswj hwm kev tsim khoom thiab tshuaj xyuas cov khoom raw.
Txhim khu kev khaws cia thiab saib cov ntaub ntawv raw; Sim siv cov xim masterbatches los ntawm tib lub chaw tsim khoom thiab txhaj tshuaj molding tshuab hom ntau li ntau tau los tsim cov khoom qub; Hais txog cov xim masterbatch, sampling thiab xim kuaj yuav tsum tau ua ua ntej loj ntau lawm, thiab piv nrog rau yav dhau los thiab tam sim no batch. Yog tias qhov sib txawv xim tsis tseem ceeb, nws tuaj yeem suav tias tsim nyog, ib yam li cov xim master batch muaj xim txawv me ntsis.
Txhawm rau txo cov xim sib txawv los ntawm kev sib xyaw tsis sib xws ntawm masterbatch nws tus kheej, peb tuaj yeem sib xyaw cov masterbatch los ntawm qhov pib thiab tom qab ntawd rov siv dua. Nyob rau tib lub sijhawm, peb kuj yuav tsum tau sim cov thermal stability ntawm cov khoom siv cob thiab xim masterbatch. Hais txog cov khoom uas tsis zoo thermal stability, peb xav kom manufacturers hloov lawv.
5, Tus tswv ntawm lub hwj chim kub thiab masterbatch ntawm cov khoom hloov xim
Ua ntej kho cov xim sib txawv, peb kuj yuav tsum nkag siab txog qhov sib txawv ntawm cov xim hloov hauv kev txhaj tshuaj molding tshuab khoom nrog kub thiab xim masterbatch; Raws li qhov kub thiab txias ntau lawm lossis masterbatch hloov pauv, cov cai hloov xim ntawm cov khoom kuj txawv; Hloov cov cai tuaj yeem lees paub los ntawm cov txheej txheem kuaj xim; Nws yog tsis yooj yim sua kom kho cov xim sib txawv sai sai tshwj tsis yog tias koj paub cov cai hloov xim ntawm masterbatch.
