Yog vim li cas thiab kev tiv thaiv rau scorch

Peb paub tias tag nrho cov txheej txheem los ntawm fkm raw cov ntaub ntawv rau fkm roj hmab cov khoom feem ntau mus los ntawm ob peb theem, feem ntau suav nrog: fluoroelastomer nyoos roj hmab, sib tov, vulcanization. Ua ntej pib ntawm vulcanization theem, peb cia siab tias cov roj hmab yuav nyob twj ywm hauv cov roj hmab nyoos, uas yog, cov roj hmab macro-molecule saw tsis tau dhau los ntawm peb-dimensional cross-linking cov tshuaj tiv thaiv. Yog tias cov roj hmab tau dhau los ua vulcanization thaum ntxov thaum lub sijhawm ua thiab khaws cia ua ntej vulcanization theem, peb hu qhov tshwm sim scorch.

Cov yam tseem ceeb uas cuam tshuam rau cov roj hmab vulcanization muaj xws li cov mis, qhov kub thiab txias, lub sij hawm, siab, thiab lwm yam, ntawm cov tseem ceeb tshaj plaws yog thawj peb. Tau kawg, cov mis ntawm no suav nrog ob qho tib si cov qauv ntawm cov khoom siv raw thiab cov mis ntawm vulcanizers thiab accelerators. Hauv qab no peb txheeb xyuas qhov ua rau roj hmab scorch los ntawm peb yam:

 

1. Cov qauv

Lub vulcanization system yog teeb tsa tsis raug, thiab cov kev tshwm sim tshwj xeeb suav nrog:

(1) Tus nqi ntawm vulcanizer thiab accelerator tshaj tus qauv;

(2) Qhov ntsuas kub tseem ceeb ntawm cov vulcanizer thiab accelerator tsawg dhau, uas yog, cov roj hmab molecular saw ua rau peb qhov sib txuas sib txuas ntawm qhov kub qis;

(3) Tus nqi ntawm cov tshuaj tiv thaiv scorch tsis siv.

 

2. Kub

(1) Kev ua haujlwm kub: Qhov kub ua haujlwm siab dhau lawm, thiab tsis muaj kev ntsuas cua txias zoo thaum ua haujlwm, ua rau cov khoom kub thiab vulcanization ntau dhau;

(2) Kev khaws cia kub: chav tsev kub ntawm lub tsev khaws khoom yog siab dhau lawm thiab tsis muaj qhov ntsuas cua txias, thiab cov khoom siv tau ntim ntau dhau, ua rau qhov kub tsis tuaj yeem poob sai;

(3) Cov ntaub ntawv loj: Yog tias cov ntaub ntawv tuab tuab heev, cov khoom siv kub yuav tsis tuaj yeem poob sai, ua rau scorch.

 

3. Sijhawm

(1) Lub sijhawm ua haujlwm: Lub sijhawm ua haujlwm ntev dhau lawm thiab dhau sijhawm cov khoom scorch, ua rau scorch;

Lub sijhawm khaws cia: Cov phiaj xwm kev noj cov khoom siv tsis yog cov ncauj lus kom ntxaws txaus, kev tswj xyuas tsis zoo, thiab cov khoom siv tseem tau muab tso rau tom qab lub sijhawm scorch tag. Thawj cov khoom tsim tawm yog nyob rau sab hauv ntawm lub tsev rau khoom, thiab nws tsis tuaj yeem nqa tawm thaum xav tau, ua rau lub sijhawm cia ntev dhau.

 

4. Pwm paug

Bisphenol curable FKM lossis Peroxide curable FKM tsis tuaj yeem kov nrog Sulfur. Cov khoom siv roj hmab yuav scorch yog tias cov pwm lossis cov kab ntau lawm tsis huv txaus.

 

Tom qab nkag siab qhov ua rau scorch, peb tuaj yeem tsim cov hom phiaj los tiv thaiv scorch, uas kuj tau piav qhia los ntawm peb yam:

1. Cov qauv:

(1) Rationally configure vulcanization system thiab tswj tus nqi ntawm vulcanizer thiab accelerator siv;

(2) Sim siv cov accelerators nrog cov tshuaj tiv thaiv siab kub;

(3) Siv cov tshuaj tiv thaiv scorching.

 

2. Kub:

(1) Kev ntsuas kub: tswj qhov kub thiab txias thaum sib tov, thiab xyuas kom cov khoom siv txias txias, tshwj xeeb tshaj yog cov menyuam kub;

(2) Cia qhov kub thiab txias: Siv sij hawm ntsuas cua txias tom qab sib tov, xws li khaws cia hauv qhov txias txias kom sai li sai tau, tswj qhov siab thiab qhov sib txawv thaum stacking, thiab txo qhov kub ntawm cov khoom siv kom sai li sai tau;

(3) Cov ntaub ntawv loj: Daim ntawv loj yuav tsum tsis txhob tuab heev

 

3. Sijhawm:

(1) Lub sijhawm ua haujlwm: Tswj lub sijhawm ua haujlwm, thiab lub sijhawm sib xyaw yuav tsum tsis txhob ntev dhau;

(2) Lub Sijhawm Cia: Tsim kom muaj cov txheej txheem siv cov ntaub ntawv ntxaws thiab cov cai khaws cia, xws li stacking cov ntaub ntawv ua tiav ze rau sab nraud ntawm lub tsev rau khoom kom yooj yim nkag tau thaum siv. Npaj kev tsim khoom raws li tus nqi ntawm cov ntaub ntawv siv kom tsis txhob muaj cov khoom siv tsis siv sijhawm ntev.

 

4. Pwm paug

Rau Bisphenol curable FKM los yog Peroxide curable FKM, cov kab ntau lawm yuav tsum nruj me ntsis tiv thaiv kom tsis txhob muaj leej faj.

 

Cov khoom siv scorch lub sij hawm tuaj yeem txuas ntxiv tau zoo los ntawm kev kho cov qauv, tab sis nws yuav tsum tau muab sau tseg tias lub sij hawm scorch tsis tuaj yeem txuas ntxiv mus rau qhov muag tsis pom, vim tias lub sij hawm scorch ntev heev yuav cuam tshuam rau cov vulcanization efficiency thiab yog li ua rau tus nqi ntawm lub Hoobkas tau nce. Txoj hauv kev kom raug yuav tsum yog los tswj lub sijhawm scorch nyob rau hauv qhov tsim nyog ntau yam, uas yuav tsis cuam tshuam rau kev tsim khoom ntawm kev lag luam thaum tiv thaiv scorch. Chengdu Crestmat Co., LTD, raws li cov khoom siv roj hmab sib xyaw nrog 20 xyoo ntawm kev tsim khoom, tau txais lub koob npe zoo hauv kev lag luam nrog nws cov cuab yeej siv siab heev thiab cov khoom zoo ua ntej muag thiab kev pab cuam tom qab muag, thiab tuaj yeem muab cov neeg siv khoom. FKM, HNBR, FVMQ, ACM, AEM thiab lwm yam khoom hauv ib qho chaw nres tsheb.
