ABS-mapurasitiki: unhu, zvakanakira nekuipira

A zvinhu zvakadai abs-mapurasitiki, kwakakurumbira chaizvo uye ari kudiwa kweShanduro zhinji yemagetsi uye namano midziyo yemagetsi. Saka, kusiyana mapurasitiki acho ane mukuru chaitwa, nokuda kwayo yakakwirira kuramba zvokuimba kukuvadza uye kudzivirirwa dzezvakatipoteredza zvinhu. Chii rokukurumidzira abs-mapurasitiki, uye chii ayo zvakanakira?

mamiriro

Izvi zvinhu ndiyo refu kwechirwere thermoplastic nebwe riri mumutauro nesayenzi inonzi "copolymer, acrylonitrile-butadiene-styrene". Izvi zvinhu ane ehupfumi nowenyika akangofananawo epurasitiki. kazhinji ruvara yayo yellowish ruvara. Zvisinei, pamusika yepasi pose kwakakurumbira abs-mapurasitiki mu segirazi marozari. Asi chero mumvuri raakanga asina kupendwa, chero zvazvingava, mashoko acho chaizvo zvakanaka anopa coloring pamusoro, kunyange kana iwe watova imwe mumvuri.

Kuburikidza mubatanidzwa butadiene uye acrylonitrile pamwe styrene zvinhu abs epurasitiki pepa rine mukuru simba uye elasticity zvivako. Saka, unogona muchanyauswa mukati kwazvo siyana, uye haina chisanyanya operative unongotaura. Naizvozvo, abs-mapurasitiki ndechimwe chezvinhu wakashandiswa pakuburitswa uye upfumi nezvinhu. Panzira, iri bhizimisi richiwanika muchimiro yunifomu granules. Kubva kwavari, kambani uye kambani inobereka zvakasiyana siyana chinoumbwa, kureva boka anokosha Polymers.

Sei chaizvo epurasitiki abs?

Zvinoitwa ichi zvinhu hakurevi haina kunyanya kwakasiyana mumwe, asi, pasinei ichi, muRussia kunoratidzwa nemazita akawanda. Izvi rakapfupikiswa chidimbu "ABS", "ABS", uye siyana mazita kwesayenzi akadai "acrylonitrile copolymer, styrene-butadiene" kana "ABS copolymer".

zvakwakanakira

Abs-mapurasitiki rakanakira zvakawanda pamusoro dzimwe mhando polymeric zvinhu. The wokutanga zvayo yakakwirira kuramba alkalis, girisi, peturu nezvimwe kungatikanganisa nevamiririri. Nepo dzimwe mhando epurasitiki angangova uchanyauka kana discolor mbeu pasi zvavo simba, kuti ABS copolymer zvichaita ainyatsoshandisa batisisa kwenguva yakareba sezvingabvira. Uyezve, pose ichi zvinhu anoenda kumeso chaizvo uye kupenyerera. zvinenge zvose ano mobile phones, Nokuda ichi, dzimba chakagadzirwa ABS epurasitiki. Muchiitiko chino, pane matte Polymers uye zvinhu, aine pamwero kwahwo.

kutadza

Pakati chikuru zvazvakashatira ichi zvinhu iye kucherechedza zvayo pasi kuramba ultraviolet chezuva (dzimwe mhando kutya dzokupisa benzene, acetone uye ethyl chloride), izvo zvingaita kuti atindivare pamusoro pemvura. Uyewo kusiyana polystyrene mapurasitiki ane pasi zvemagetsi insulating ehupfumi. Zvisinei, kuvapo nezvekukanganisa izvi hazvina kumutadzisa kuenda nechivimbo kutora aitungamirira chinzvimbo ndandanda polymeric zvokuvakisa pagadzirwe siyana epurasitiki zvigadzirwa.
