Lub ntsiab lus ntawm Dip Txheej thiab Dip Moulding

Txheej txheem ntawm Dip Txheej thiab Dip Moulding

Dip txheej

Cov txheej txheem ntawm fusing cov khoom yas mus rau ib qho khoom hlau uas twb muaj lawm yog hu ua dip txheej. Cov hlau yuav tsum tau coated ua hauj lwm ua pwm, cia cov yas los yog polymer ua raws li nws thaum lub sij hawm txheej txheem. Ua ntej dipping, cov khoom (thiab qee zaum tag nrho cov khoom) npaj rau dipping yog kho thiab preheated ua ntej muab tso ncaj qha rau hauv cov kua polymer (xws li. PVC plastisol ). Thaum txias, cov kua polymer adheres rau hlau thiab solidifies, uas ua rau ib tug tuab yas txheej txheej uas muaj ob qho tib si tiv thaiv thiab zoo nkauj zog. Qhov kev txhim kho saum npoo no muaj zog tiv thaiv khawb, hnav, corrosion, thiab lwm yam tseem ceeb thaum tseem txhim kho durability thiab ncua kev pab cuam lub neej ntawm hlau qhov chaw. Dip txheej tsis tsuas yog muab kev yooj yim xwb tab sis kuj ua kom cov neeg siv kev nyab xeeb los ntawm kev muab ib qho chaw insulating nrog txhim kho tuav.

Kev siv cov txheej txheej txheej muaj xws li cov cuab yeej siv tes xws li cov pliers uas tau txais txiaj ntsig los ntawm lawv lub peev xwm los nthuav lossis khoov cov ntaub ntawv nruj thaum khaws cov cuab yeej kev ncaj ncees tom qab siv cov txheej txheem yas ntawm tes. Tsis tas li ntawd, dip coatings pom cov khoom siv hauv ntau lwm yam khoom xws li lub tawb nqa khoom, pob tawb, tweezers, hau, kaus mom, stoppers thiab lwm yam, qhov twg xav tau rigidity.

Tsis tas li ntawd, cov txheej yas ua haujlwm zoo li cov thermal thiab hluav taws xob insulators muab kev tiv thaiv ntxiv thaum tuav cov khoom kub hauv tes xws li pliers thiab shovels; lawv kuj tuaj yeem siv rau cov laj thawj rwb thaiv tsev hauv cov khoom siv hluav taws xob xws li xov hlau, cables, thiab cov ntsuas ntsuas digital.

Txhaj Molding

Cov txheej txheem ntawm dip molding yog zoo ib yam li dip txheej, nrog rau kev ntxiv ntawm demoulding los yog unloading kauj ruam. Dip molding tso cai rau kev tsim cov phab ntsa ib leeg, hollow, thiab ob chav phab ntsa, tshem tawm qhov xav tau rau cov txheej txheem tom ntej xws li trimming thiab deburring. Qhov no ua rau kev txuag cov khoom siv raw vim txo qis kev ua haujlwm theem nrab. Piv txwv ntawm cov khoom yas tsim los ntawm cov txheej txheem no suav nrog cov hnab looj tes latex, zam thiab khaub ncaws accessories, khob, hau yas, thiab cov khoom siv lom zem.

Hom Dip txheej thiab Moulding Polymer

Feem ntau siv cov polymers rau txheej txheej muaj xws li plastisol, latex, neoprene, polyurethane, thiab epoxy. Ib tug yam ntxwv tseem ceeb ntawm cov polymers no yog lawv lub peev xwm ua tau yooj yim nyob rau hauv cov ntaub ntawv ua kua nyob rau hauv chav tsev kub yam tsis tas yuav tsum tau ua ntxiv. Ntxiv mus, ua ntej xav txog kev siv cov kua polymer hauv cov txheej txheem dip thiab dip molding txheej txheem, nws yuav tsum muaj viscosity txaus los tiv thaiv cov dej ntws ntau dhau los ntawm cov pwm saum npoo. Yog li ntawd, cov polymer nyob rau saum npoo kom txog thaum nws raug kho.

Plastisol

Plastisol, feem ntau siv polymer nyob rau hauv dip molding thiab dip txheej txheej txheem, muaj finely dispersed polyvinyl chloride (PVC) resin nyob rau hauv ib tug kua plasticizer. Thaum cua sov, nws solidifies thiab tom qab txias mus rau hauv ib tug mos, elastic cov ntaub ntawv uas zoo li roj hmab. Renowned rau nws tshwj xeeb toughness, corrosion kuj, thiab cuam tshuam tsis kam, Plastisol coatings yog tshwj xeeb tshaj yog haum rau hluav taws xob daim ntaub ntawv vim lawv siab dielectric zog. Tsis tas li ntawd, cov xim pleev xim tuaj yeem muab tso ua ke los kho qhov kawg ntawm cov khoom zoo li.

looj

Cov emulsion ntawm latex muaj cov khoom me me, nrog cov khoom siv roj hmab suav txog 30-40% ntawm tag nrho. Nws ua haujlwm raws li cov khoom siv tseem ceeb hauv kev tsim cov roj hmab thiab tuaj yeem yog ntuj lossis hluavtaws. Lub polymer yog yooj yim nkag tau thiab poses tsis muaj toxicity kev txhawj xeeb. Txawm li cas los xij, qee qhov kev tshawb fawb qhia tias thaum nws degrades rau hauv cov hmoov hmoov, qee tus neeg yuav muaj kev tsis haum tshuaj, ua rau muaj kev poob qis hauv nws qhov chaw.

neoprene

Neoprene yog tsim los ntawm polymerization ntawm neoprene roj hmab thiab yog lwm txoj hauv kev latex. Nws paub txog nws cov tshuaj tiv thaiv thiab yoog raws.

Polyurethanes

Polyurethanes yog tsim los ntawm carbamate (los yog ethyl carbamate) pawg txuas los ntawm carbamate. Nws yog lub npe hu rau nws yooj yooj yim thiab siab elasticity rau deformation.

Epoxy

Epoxy yog ib qho thermosetting polymer uas, thaum lub polymer chains cross-linked, tsim ib txheej ntawm lub zog siab, tshuaj lom neeg thiab kub ua hauj.
