Ntau cov khoom siv roj hmab yog molded, thiab tom qab molding, vulcanization kom tau cov khoom uas tsim nyog lub cev muaj zog, cov tsos ntawm cov khoom tsis muaj qhov tsis xws luag, tab sis cov pa trimming txoj kev tsis tuaj yeem kho cov kev xav tau ntawm cov khoom, muaj cov burrs me me tsis tuaj yeem raug tshem tawm, phau ntawv kho lossis scrapping ua rau muaj kev lag luam pov tseg ntau.

Lub sijhawm no, kev tsim qauv ntawm cov pwm clamping kab ntawm cov khoom yog qhov tseem ceeb tshwj xeeb, yuav ua li cas los tsim daim di ncauj, hla kab thiab dhau qhov zawj, thiab lwm yam, yuav tsis tau piav qhia ntawm no, koj tuaj yeem xa mus rau 'Rubber Pwm Design Manual'.

Lub hom phiaj ntawm tsab xov xwm no yog piav qhia los ntawm cov qauv thiab cov txheej txheem, vim tias cov pwm feem ntau tsim tsis tuaj yeem hloov kho lossis khawb cov pwm (kev lag luam pov tseg), feem ntau nrhiav ib tus kws tsim qauv los hloov cov qauv los yog hloov cov txheej txheem kom ua tau yooj yim tearing.

Ntawm no, nws tsis pom zoo kom kho cov mis tsis tu ncua, vim tias kev hloov kho cov mis feem ntau cuam tshuam nrog seb muaj ntau lub cev thiab tshuaj ntsuas hauv lub cev ua tau raws li daim ntawv thov ntawm cov khoom siv roj hmab, yam tsis muaj ado ntxiv, ncaj qha rau kev daws:

1. Vim yog cov txheej txheem kub (sib tov, smelting, chaw nres tsheb), me ntsis scorching tshwm sim los ntawm (qee zaum lub rheometer saib ntawm vulcanization keeb kwm daim ntawv ML, TS1 thiab lwm yam pib fluidity thiab fluctuations), uas ua rau nyuaj rau trimming.

Kev daws: nce tus nqi ntws ntawm cov khoom sib tov dej txias los yog siv lub tshuab pwm txias txias (nruam ntxuav cov calcium scale ntawm cov kav dej); Lub zeb tuaj yeem laum cov menyuam los ua kom cov dej txias hauv cov menyuam kom txo tau qhov kub thiab txias (txoj kev tov khoom kuj tseem siv tau); Chaw nres tsheb kom sai li sai tau kom txo tau qhov kub thiab txias rau hauv chav tsev, nws tsis pom zoo kom muab tso rau hauv ntau qhov ntau, uas tuaj yeem ua rau kub kub nruab nrab thiab ua rau scorching.

2. Lub dispersion ntawm cov khoom siv roj hmab tsis sib xws, thiab nws yog ib qho nyuaj rau rhuav tshem ntawm ntug uas tshwm sim los ntawm cov khoom siv hauv zos siab.

Kev daws: Tsim nyog npaj qhov kev txiav txim thiab lub sijhawm ntawm cov khoom xa tuaj, cov khoom tawg thiab melting ua tau raws li cov txheej txheem, thiab cov roj hmab dispersion additives tuaj yeem tsim nyog ntxiv rau hauv cov qauv tsim.

3. Qhov kub ntawm vulcanization yog siab dhau, ua rau cov npoo nkig.

Kev daws: xaiv qhov kub ntawm vulcanization nrog cov khoom tsim nyog, tsis tuaj yeem ua qhov muag tsis pom kev tsim cov peev txheej, kev puas tsuaj rau entropy ntawm roj hmab thiab qib ntawm vulcanization hauv zos qauv txawv.

4. Lub vulcanized roj hmab ntug tsis sib npaug hauv thickness thiab pwm daim di ncauj yuam kev yog loj.

Kev daws: Hloov cov pwm kom ua tau raws li qhov yuav tsum tau ua yuam kev thiab ua tau raws li qhov xav tau ntau lawm.

5. Lub Mooney ntawm cov khoom siv roj hmab yog loj, thiab 'Green zog' ntawm cov khoom siv roj hmab yog loj.

Kev daws: Nws tuaj yeem ua tau plasticized, txo cov plasticity, thiab txhim kho fluidity ntawm roj hmab; Lub formulation txiav txim siab lub Mooney viscosity thiab Mooney scorching ntawm lub compound.

6. Lub fluidity ntawm cov khoom siv roj hmab tsis zoo.

Kev daws: Thaum tsim cov qauv, xav txog qhov fluidity, ntxiv cov khoom siv ntxiv, cov khoom tawg, cov khoom muag thiab cov resins, thiab lwm yam, txhawm rau txhim kho cov dej ntws ntawm cov khoom siv roj hmab, tab sis kev sib xyaw ua ke yuav tsum ua tau raws li cov khoom tsim thiab cov txheej txheem tsim khoom.

7. Lub ntug dej ntawm cov khoom siv roj hmab yog tuab thiab tsis tuaj yeem tawg.

Kev daws: nce siab ntawm vulcanization pwm; Pwm hloov kho kom tau raws li qhov yuav tsum tau ua; Txo cov Mooney (stiffness) ntawm qhov sib xyaw, kom cov roj hmab tau zoo dua 'softness' thiab fluidity.

8. Cov qauv tsim tsis tsim nyog.

Kev daws teeb meem: Vim tias cov qauv raug txiav txim siab hauv ntau yam, kom ua tau raws li qhov xav tau ntau lawm, cov khoom tsim tsis tau thiab kev tsim nyog tus nqi, thiab lwm yam. Cov qauv tsim tshwj xeeb tuaj yeem nrhiav tau hauv peb lub studio los tsim cov nqi tsim nyog thiab lub Hoobkas tsim qauv tsim nyog.

9. Lwm yam laj thawj: tsis tsim nyog cia, tsis ua hauj lwm los yog agglomeration ntawm cov ntaub ntawv; Lub sij hawm scorching ntawm raw roj hmab xaiv tsis ruaj khov; Cov kua nplaum sib xyaw tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm 'kua theem mixing'; vulcanization system; Accelerator sib txuam; filler particle loj faib; Resin melting thiab lwm yam.
