Roj Hmab Molding Txhaj Moulding rau cov khoom siv roj hmab

Compression Moulding

Nyob rau hauv compression molding, cov roj hmab compound yog muab tso rau hauv lub pwm kab noj hniav, thiab lub siab yog siv rau compress cov khoom rau hauv lub siab xav. Thaum tshav kub kub yog ua hauj lwm los kho cov roj hmab. Txoj kev no feem ntau yog siv rau kev tsim khoom xws li gaskets, seals, thiab cov khoom siv tsheb.

Txhaj Molding

Txhaj tshuaj molding entails txhaj cov roj hmab molten rau hauv pwm nyob rau hauv siab. Cov txheej txheem no yog qhov zoo tagnrho rau kev tsim cov khoom sib txawv thiab meej, nrog rau cov khoom siv tsheb thiab cov khoom siv. Overmolding thiab insert molding yog variations ntawm cov txheej txheem no, nrog rau kev koom ua ke ntawm tiav hlau qhov chaw rau hauv pwm kab noj hniav ua ntej txhaj roj hmab.

Hloov Molding

Kev sib xyaw ua ke ntawm compression thiab txhaj tshuaj molding, hloov molding siv cov roj hmab ntsuas hauv ib lub rhuab chamber. Lub plunger yuam cov khoom rau hauv pwm kab noj hniav, ua rau nws tsim nyog rau kev tsim hluav taws xob connectors, grommets, thiab me me precision qhov chaw.

Extrusion

Extrusion yog ua haujlwm los tsim kom ntev ntev ntawm cov roj hmab nrog cov duab sib luag, xws li hoses, tubing, thiab profiles. Cov roj hmab raug yuam los ntawm kev tuag kom ua tiav qhov kev xav tau.

Kev kho (Vulcanization)

Kev kho, lossis vulcanization, cuam tshuam nrog kev sib txuas ntawm cov roj hmab polymer chains los txhim kho lub zog, elasticity, thiab kub tsis kam. Qhov no yog ua tiav los ntawm kev siv cov cua sov thiab siab rau cov khoom siv roj hmab molded, nrog rau ntau txoj hauv kev xws li chav, cua kub, thiab microwave curing.

Roj hmab rau hlau Bonding

Cov txheej txheem tshwj xeeb, roj hmab rau hlau sib txuas tsim cov khoom lag luam sib koom ua ke ntawm cov roj hmab yooj yim nrog lub zog ntawm cov hlau. Cov roj hmab tivthaiv yog preformed lossis molded, muab tso rau ntawm cov hlau nto nrog cov nplaum, thiab tom qab ntawd raug tshav kub thiab siab rau vulcanization lossis kho. Cov txheej txheem no chemically khi cov roj hmab rau cov hlau, tsim kom muaj kev sib txuas ruaj khov thiab ruaj khov tseem ceeb heev rau cov ntawv thov uas xav tau ob qho kev vibration dampening thiab kev txhawb nqa.

Kev sib xyaw

Kev sib xyaw ua ke muaj kev sib xyaw cov khoom siv roj hmab nrog ntau yam khoom siv los tsim cov roj hmab sib xyaw nrog cov khoom tshwj xeeb. Cov additives yuav muaj xws li curing agents, accelerators, antioxidants, fillers, plasticizers, thiab colorants. Qhov kev sib xyaw no feem ntau ua nyob rau hauv ob-yob zeb los yog ib qho khoom siv sab hauv kom ntseeg tau tias qhov sib txawv ntawm cov khoom ntxiv.

Milling

Tom qab kev sib xyaw ua ke, cov roj hmab sib xyaw ua rau cov txheej txheem milling lossis sib xyaw ua ke kom ua kom homogenize ntxiv thiab tsim cov khoom. Cov kauj ruam no tshem tawm cov npuas npuas thiab lav qhov sib xws hauv qhov sib xyaw.

Tom qab ua tiav

Tom qab kho, cov khoom siv roj hmab yuav dhau los ua cov txheej txheem ntxiv, suav nrog kev txiav, deflashing (tshem tawm cov khoom siv ntau dhau), thiab kev kho deg (xws li txheej lossis polishing) kom ua tau raws li cov cai tshwj xeeb.

Ntuj Roj Hmab (NR):

Muab tau los ntawm cov kua txiv hmab txiv ntoo ntawm tsob ntoo roj hmab (Hevea brasiliensis), cov roj hmab ntuj paub txog nws cov elasticity thiab resilience. Feem ntau siv rau hauv daim ntawv thov xws li cov log tsheb, khau, thiab cov khoom siv, nws muaj kev txwv tsis pub ua kom sov thiab tshuaj.

Synthetic Roj Hmab:

Tsim los ntawm cov txheej txheem tshuaj lom neeg, cov khoom siv hluavtaws muaj ntau yam khoom. Qee hom muaj xws li:
