Yintoni iPolyphenylene Sulphide (PPS)
I-PPS imele i-Polyphenylene Sulphide yi-thermoplastic yobunjineli yobuchule obuphezulu eyohlulwe ngokudityaniswa kwayo kweepropati.
Yi-semi-crystalline, i-opaque kunye ne-polymer eqinile enendawo yokunyibilika ephezulu kakhulu (280 ° C) kwaye iquka iiyunithi ze-para-phenylene ezitshintshana kunye noqhagamshelwano lwazo lwesulfide.
I-PPS inomlinganiselo ogqwesileyo weempawu ezifana nokuxhathisa idangatye, ukuxhathisa okulungileyo kweekhemikhali, ukumelana nobushushu obuphezulu, ubuchule bobukhulu, amandla akhethekileyo omatshini kunye nokugqunyelelwa kombane.
I-PPS inokucutshungulwa ngokulula kuba ukuqina kwayo kunyuka ngamaqondo obushushu aphezulu.
Zonke ezi mpawu zimangalisayo zenza i-PPS ibe yeyona ndlela ibalaseleyo kwi-thermosets kunye nesinyithi ukuze zisetyenziswe kwizicelo ezininzi kunye nezixhobo zombane, iinxalenye zemoto kunye ne-elektroniki.
Abathengi abaninzi kwiindawo zokubumba inaliti ye-PPS banohlobo lokucinga lwe-inertia: akukho bushushu bomngundo, isango alilikhulu, ukukhupha okunganelanga, ixesha elifutshane lokupholisa.
Ubushushu bomngundo bunokwenza umphezulu wemveliso ukhawuleze icrystallization, ugudileyo ngaphandle kokuhamba kwefayibha edadayo, eyona nto ibalulekileyo kukwenza ukomelela kwemveliso yomeleze kakhulu; ubungakanani besango buchaphazela ubungakanani benaliti yeplastiki, kwaye kuya kubakho iimfuno zokumisela uxinzelelo kunye nesantya sokujova. Kuya kuba nefuthe kwilahleko yoxinzelelo lwe-distal yeemveliso zamanqaku amaninzi.
Ukukhutshwa okungonelanga kuya kubangela ukuqokelela ngokukhawuleza kwegesi, okubangela ukutshisa kunye nephethini ebusweni kunye nomsila wemveliso.
I-PPS ngokwayo imathiriyeli iya kuqulatha i-sulfide kunye nesinye isixa esincinci se-polyphenylbiphenyl polymer precipitation, ngoko ke uyilo lokukhupha lubaluleke kakhulu!
Ixesha elifutshane lokupholisa, alihambisani ne-crystallization epheleleyo yemveliso!
Ukuze uphishekele umthamo wokuvelisa, abathengi abaninzi banciphisa ngokuthe ngqo umjikelezo wemveliso ukuya kwinqanaba elikhulu, okubangela umjikelezo we-crystallization wezinto ezimfutshane, ongenakuncedo kwisisombululo sento yokuqala!
Ukukhetha okunengqiqo kwemathiriyeli, ukuveliswa kwenzululwazi!
Ukubonelela ngenkxaso yokumisa enye kwizinto eziluhlaza, ukubumba, iinkqubo, iimveliso ezigqityiweyo, izikhalazo zabathengi kunye nolunye uchungechunge olupheleleyo!
Izinto zokusebenza eziphezulu ezikujikelezile iingcali zesisombululo esisodwa!
