Sechinhu chakakosha chemidziyo yakasiyana-siyana, fenicha nezvishandiso, zvinhu uye mashandiro ezvishandiso zvine chekuita zvikuru nemhando uye mashandiro echigadzirwa chose. Pakati pemhando dzakawanda dzezvishandiso, zvishandiso zveTPR nezvishandiso zverabha zveBR isarudzo mbiri dzakajairika. Nhasi tichaongorora mutsauko uripo pakati pemhando mbiri idzi dzezvishandiso zveBR neTpr.
Zvishandiso uye Zvivakwa
Chekutanga, maTPR casters akagadzirwa nethermoplastic rabber (TPR), chinhu chinogadzirwa nethermoplastic chine rabber elasticity, chisingadi kupiswa uye chine hushamwari kune nharaunda, hachina chepfu, uye chine mavara akajeka. Nekuda kwekupfava uye kuramba kupfava kwezvinhu zvinogadzirwa neTPR, maTPR casters anowanzo dzivirira kupwanyika, mafuta uye mamiriro ekunze zvakanaka.
Kusiyana neizvi, maBR rabha casters anogadzirwa ne butadiene rabha (BR), rabha yakagadzirwa yakagadzirwa kubva mu polymerization ye butadiene monomers, ine chimiro chemamorekuru chakafanana neche rabha yechisikigo. BR rabha ine kutwasuka kwakanaka, inodzivirira kukwesha, inodzivirira kutonhora, uye inodzivirira kuchinjika.
Kugadzirisa uye mashandiro
Kushanda zvakanaka kweTPR zvinhu zviri mudura kuri nani pane kuita rabha, uye inogona kugadziriswa nemidziyo yemazuva ese yethermoplastic isina mushonga we vulcanization. Izvi zvinoita kuti TPR casters ishande zvakanaka uye isadhure kugadzira.
Zvisinei, maBR rabha casters anobudirira zvikuru mukushanda kwakasimba, kunyanya pakupisa kwakanyanya.BR rabha ine simba rakanaka rekudzivirira kukwesha, kuramba kupwanyika, uye kuramba kubvaruka, izvo zvinoita kuti maBR rabha casters arambe achishanda zvakanaka munzvimbo dzakaoma.
Kudzivirirwa uye kuchengetedzeka kwezvakatipoteredza
Panyaya yekuchengetedzwa kwezvakatipoteredza, zvinhu zveTPR zvine zvazvinobatsira: TPR chinhu chisina chepfu uye chisina chepfu chinoenderana neROHS, REACH nedzimwe mitemo yezvakatipoteredza, uye chinogona kushandiswa zvakanyanya mumidziyo yekurapa, matoyi evana nedzimwe nzvimbo. Kusiyana neizvi, kunyange hazvo rabha reBR ririwo chinhu chisina chepfu, rinogona kudziviswa nemitemo yezvakatipoteredza mune mamwe mamiriro ekushandiswa.
Pakusarudza macaster, kufungwa kwakazara kunofanirwa kuitwa zvichibva pazvinhu zvakaita semamiriro ezvinhu chaiwo ekushandiswa, zvinodiwa pakushanda uye mitemo yezvakatipoteredza. Semuenzaniso, macaster eTPR anogona kunge ari sarudzo iri nani mumamiriro ezvinhu anoda kugadzirwa kwepamusoro, mutengo wakaderera uye zvinodiwa zvakanyanya zvakatipoteredza, nepo macaster eBR rabha anogona kunge akakodzera mumamiriro ezvinhu ekushandisa anoda kushanda kwakasimba uye kuramba kupisa kwakanyanya.
