Thaum nws los txog rau cov khoom siv silicone, kuv ntseeg tias ntau tus phooj ywg paub txog nws. Hauv peb lub neej niaj hnub, peb feem ntau muaj cov khoom siv tiv thaiv hluav taws xob, cov xov tooj ntawm tes silicone tiv thaiv, Bluetooth hais lus tiv thaiv, thiab lwm yam, nrog rau cov khoom me me xws li silicone noj fwj thiab pacifiers. Nws tuaj yeem hais tias cov khoom siv silicone tau muaj feem cuam tshuam nrog peb lub neej. Koj puas tuaj yeem nkag siab cov txheej txheem ntawm cov khoom siv silicone? Yuav ua li cas txog cov txheej txheem ntau lawm? Nws tau nkag siab tias tam sim no muaj ob txoj hauv kev rau kev tsim cov khoom siv silicone. Ib qho yog cov khoom lag luam uas yog lub xeev molded nrog cov roj hmab sib xyaw, thiab lwm yam yog cov khoom lag luam uas tau txhaj tshuaj molded nrog kua silicone roj hmab.
Nws yog ib qho tsim nyog kom nkag siab tias cov khoom siv silicone ua los ntawm thawj txheej txheem yog vulcanized nrog peroxide, uas yuav tsum tau muaj ntau yam txheej txheem xws li roj hmab sib tov, qhib, txiav, hnyav, molding, thiab tearing. Siv cov txheej txheem no los tsim cov khoom siv silicone feem ntau yog siv rau daim ntawv thov ntawm cov khoom siv silicone qis kawg; Tsis tas li ntawd, cov khoom lag luam silicone ua los ntawm cov txheej txheem thib ob yog ncaj qha yuav rov qab ob-cov khoom ntim cov khoom ntim ntawm silicone, thiab siv cov kua silicone roj hmab txhaj tshuaj molding tshuab ncaj qha, tom qab txhim kho cov tshuab, ntws ntawm tag nrho cov khoom yog nqa tawm hauv lub kaw lus. xeev, tsis muaj kev cuam tshuam los ntawm phau ntawv, yog li nws yuav tsis muaj kuab paug. Cov khoom siv hauv cov txheej txheem no yog ua los ntawm platinum ua vulcanizer, uas yog tus phooj ywg zoo heev. Nws yog dav siv nyob rau hauv high-end kev lag luam xws li kev kho mob thiab cov khoom me nyuam mos.
Nyob rau hauv cov txheej txheem ntawm cov khoom siv silicone, cov nram qab no hom molding yog feem ntau siv. Dab tsi yog qhov txawv?
1. Extrusion txheej txheem:Ib yam li peb nyem cov tshuaj txhuam hniav, lub taub hau extrusion tseem yog cov duab ntoo khaub lig ntawm cov khoom, nrog rau qee qhov ntev. Nyob rau hauv qhov kev txiav txim ntawm kev quab yuam thiab kub, cov khoom uas tawm ntawm lub taub hau tau vulcanized thiab tsim. Cov khoom tsim los ntawm cov txheej txheem no feem ntau yog cov khoom siv strip-puab, thiab cov khoom sib dhos tuaj yeem ua ntau yam. Piv txwv li, rectangular strips, ncig silicon raj, thiab lwm yam
2. Cov txheej txheem ua kua nplaum:Cov khoom siv raw ntawm silicone roj hmab yog nyob rau hauv cov kua hauv lub xeev, thiab cov khoom siv raw yog ntim rau hauv lub syringe. Cov khoom siv raw yog dripped mus rau pwm los ntawm pneumatic thiab phau ntawv ua haujlwm, thiab tom qab ntawd rhuab thiab vulcanized rau daim ntawv. Cov txheej txheem no yog cov txheej txheem ntawm phau ntawv, yuav tsum tau ua haujlwm ntau. Yog li ntawd, productivity tsis siab. Nws muaj qhov tshwj xeeb uas cov khoom tuaj yeem raug dripped nrog ntau xim raws li qhov yuav tsum tau ua. Yog li hom khoom siv tes ua no feem ntau yog ua cov khoom siv tes ua. Piv txwv li, ntau xim silicone bracelets, silicone xov tooj ntawm tes nrog ntau yam xim qauv, thiab lwm yam
3. Solid-state kub nias molding txheej txheem:Cov txheej txheem no siv qhov kub thiab siab ntawm hydraulic xovxwm los vulcanize cov khoom nrog kev pab los ntawm pwm. Cov txheej txheem no yog tus nqi qis, siab tso tawm, thiab siv dav. Nws feem ntau yog siv rau monochrome silicone khoom. Nws kuj tseem tuaj yeem siv rau ob-xim thiab ob chav hardness khoom lossis ntau xim thiab ntau hardness khoom, tab sis cov qauv ntawm cov khoom tsis hloov pauv thiab txwv. Nws kuj tseem tuaj yeem siv rau cov yas thiab hlau cladding, uas tseem tsis yooj yim rau hauv cov qauv, thiab muaj qhov kub thiab txias rau cov khoom ntim. Feem ntau, cov khoom ntim yuav tsum tau tiv taus 180 degrees Celsius yam tsis muaj deformation.
4. Kev txhaj tshuaj molding ua kua:Cov cuab yeej xav tau rau cov txheej txheem no suav nrog lub tshuab txhaj tshuaj silicone thiab lub tshuab xovxwm. Nws cov khoom siv raw yog dej-tuab, muab faib ua ob yam, A thiab B. Nws txoj cai yog: siv lub tshuab xovxwm los nias cov khoom raw ntawm A thiab B cov khoom rau hauv lub thoob ntawm lub tshuab txhaj tshuaj raws li qhov sib piv ntawm 1: 1. , thiab ces nias nws mus rau hauv kab noj hniav ntawm cov pwm kub los ntawm lub nozzle rau daim ntawv. Lub molding kub ntawm cov txheej txheem no kuj tsis tshua muaj, 130 degrees yog txaus. Nws tuaj yeem siv rau overmolding ntawm cov yas uas tsis tshua muaj kev tiv thaiv rau qhov kub thiab txias, uas muaj qhov zoo ntawm cov khoom hauv lub xeev thermocompression molding. Nws muaj yields siab thiab yooj yim rau automate. Tab sis tus nqi ntawm cov khoom siv raw yog ob peb zaug ntau dua li cov khoom siv silica gel raw khoom.
Peb twb to taub cov txheej txheem ntawm cov khoom siv silicone, yog li dab tsi yog cov txheej txheem ntau lawm?
1. Kev xaiv khoom, xaiv cov khoom siv silicone uas tsim nyog raws li cov khoom siv ib puag ncig thiab kev xav tau zoo, xws li cov khoom hnav tsis kam, roj tsis kam, acid tsis kam, alkali tsis kam, siab thiab kub tsis kam, tensile zog, thiab lwm yam, thiab siv qhov no los txiav txim siab. yam khoom twg yog qhov tsim nyog xaiv.
2. Kev kho kom zoo. Feem ntau, cov khoom siv raw peb yuav tsuas yog cov roj hmab nyoos xwb, uas tsis tuaj yeem siv ncaj qha rau hauv kev tsim khoom, thiab kev ua haujlwm thib ob yuav tsum tau ua. Peb hu nws refining. Refining txhais tau tias ntxiv accelerators rau cov roj hmab nyoos hauv ib qho kev faib ua feem. Toner thiab lwm yam khoom xyaw molding kom tau raws li qhov yuav tsum tau ua.
3. Txiav. Tom qab refining, tag nrho cov khoom yog tau. Tom ntej no, raws li cov qauv thiab qhov loj ntawm cov khoom, tag nrho cov khoom yuav tsum tau txiav rau hauv cov khoom kawg nrog tib qhov hnyav, cov duab thiab qhov loj me raws li peb xav tau.
4. tsim. Tom qab ua tiav cov haujlwm saum toj no, cov kauj ruam tseem ceeb tshaj plaws yog tsim. Peb yuav tsum muab cov khoom txiav rau hauv cov kauj ruam dhau los rau hauv silicone roj hmab pwm, thiab ua kub nias raws li cov txheej txheem ua ntej txheej txheem kom thaum kawg tau txais yam peb xav tau. Tau kawg, kuj tseem muaj cov khoom lag luam uas tuaj yeem tau txais los ntawm kev txhaj tshuaj ncaj qha rau hauv cov pwm kab noj hniav los ntawm kev txhaj tshuaj molding tshuab es tsis txhob kub nias, uas zoo ib yam li lub hauv paus ntsiab lus ntawm lub syringe.
5. Kev ua haujlwm / tshuaj xyuas. Tom qab molding, qhov peb tau txais yog tag nrho cov khoom. Peb yuav tsum cais ib feem ntawm cov khoom peb xav tau los ntawm nruab nrab, tom qab ntawd tshem tawm cov khoom burrs, thiab tshuaj xyuas qhov zoo ntawm cov khoom. Txog tam sim no, cov khoom tsim nyog silicone roj hmab tseem ua tiav nws cov txheej txheem tag nrho.
Tau kawg, tsis yog tag nrho cov txheej txheem tsim khoom silicone yog raws li tau piav qhia saum toj no. Cov phiaj xwm tshwj xeeb yog txiav txim siab raws li qhov xwm txheej tiag tiag thiab cov neeg siv khoom zoo rau cov khoom! Nws tsis tuaj yeem hais dav dav.
