“Yintoni imathiriyeli yePPS?
I-PPS, eyaziwa ngokuba yi-Polyphenylene Sulfide (PPS), yiplastiki yobunjineli esebenza kakhulu esetyenziswa kakhulu kumashishini ahlukeneyo, kuquka imichiza, i-electronics, kunye neemoto, ngenxa yokumelana nobushushu obugqwesileyo, ukumelana neekhemikhali, kunye nokugquma kombane. Eli nqaku liza kuhlalutya ngokweenkcukacha iipropati kunye nokusetyenziswa kwePPS kunye nokubaluleka kwayo kumashishini ahlukeneyo ukukunceda uqonde ngcono ukuba yintoni iPPS.

Ukwakhiwa kweekhemikhali ze-PPS kunye neempawu

I-PPS yipolima ye-semi-crystalline eneringi zebenzene ezitshintshanayo kunye neeathom zesulfure. Iringi ye-benzene kwisakhiwo sayo sekhemikhali inika ukuqina kwe-thermal okugqwesileyo, ngelixa ii-athomu zesulfure ziphucula ukuxhathisa kweekhemikhali kunye namandla omatshini. Esi sakhiwo senza i-PPS ibe nzima kakhulu kumaqondo okushisa aphezulu, uxinzelelo kunye neendawo ezinobungozi.I-melting point ye-PPS idla ngokumalunga ne-280 ° C, evumela ukuba igcine imilo yayo kunye neepropati kumaqondo aphezulu ngaphandle kokuguqulwa okanye ukuthotywa.

IiNdawo zeSicelo sePPS

Ngenxa yeempawu zayo ezizodwa, i-PPS isetyenziswa kuluhlu olubanzi lwamashishini. Kwishishini lemichiza, i-PPS isetyenziswa ngokuqhelekileyo ekwenzeni iimpompo, iivalvu, iipayipi kunye ne-linings yezixhobo zekhemikhali ngenxa yokumelana kwayo neekhemikhali. Kwintsimi yombane kunye ne-electronics, i-PPS isetyenziselwa ukuveliswa kwezihlanganisi, iiswitshi kunye nezinye izinto ze-elektroniki ngenxa yokutshatyalaliswa kombane okugqwesileyo kunye nokuqina kobushushu obuphezulu.

Iinzuzo kunye nemingeni yePPS

Iinzuzo eziphambili ze-PPS ziquka ukuxhathisa ubushushu obuphezulu, ukuxhathisa imichiza, amandla aphezulu omatshini kunye nokuzinza okuhle kwe-dimensional. kukwakho nemingeni ethile ngemathiriyeli yePPS. Ukuqina kwePPS kumaqondo obushushu asezantsi akulunganga, okunokuthi kuthintele ukusetyenziswa kwayo kwindawo ezibanda kakhulu. ukusetyenzwa kwezixhobo ze-PPS kunzima, kufuna ukubunjwa kumaqondo aphezulu, okubeka iimfuno eziphezulu kwizixhobo zokuvelisa kunye neenkqubo. Ixabiso lempahla ekrwada yePPS liphezulu, elinokuthi lichaphazele amandla ayo okusetyenziswa kwindawo ebandayo. Ixabiso eliphezulu lemathiriyeli ekrwada ye-PPS inokuchaphazela ukukhuthazwa kwayo kwezinye iimarike ezingevani namaxabiso.

Iintsingiselo zexesha elizayo zePPS

Ngokukhula kwemfuno yezinto eziphezulu zokusebenza, ukusetyenziswa kwezixhobo zePPS kuthembisa kakhulu. Kwixesha elizayo, ngokuphuculwa kwenkqubo yokuvelisa kunye nophuhliso lobuchwepheshe bokuguqulwa kwezinto, ukusebenza kwe-PPS kulindeleke ukuba kuphuculwe ngakumbi kwaye iindawo zokufaka izicelo ziya kwandiswa ngakumbi. Ngokukodwa kwintsimi yezithuthi zamandla amatsha, i-aerospace kunye nokuveliswa okukrelekrele, imfuno yezinto zePPS kulindeleke ukuba ikhule kakhulu.

Isishwankathelo

Yintoni i-PPS?PPS sisixhobo sepolymer esinentsebenzo egqwesileyo, ethe yasetyenziswa ngokubanzi kumashishini aliqela ngenxa yokumelana nobushushu obugqwesileyo, ukuxhathisa imichiza kunye namandla omatshini. Nangona kukho imingeni, izixhobo zePPS ziya kuqhubeka zidlala indima ebalulekileyo kwixesha elizayo kwiindawo ezininzi ngenxa yeempawu zazo ezizodwa. Ukuqonda iipropathi kunye nokusetyenziswa kwePPS kuya kusinceda ukuba sisebenzise ngcono le mathiriyeli yokusebenza okuphezulu ukuhlangabezana nemingeni yoshishino lwangoku. "
