Izindaba

Ipayipi lepulasitiki liyinto ejwayelekile yokufaka amapayipi eye yasetshenziswa kabanzi emikhakheni eminingi ngenxa yokwakheka kwalo okuqinile, izindleko eziphansi, ulula, kanye nokumelana nokugqwala. Okulandelayo yizinto eziningana ezivamile zamapayipi epulasitiki kanye nezindawo zokusetshenziswa kanye nezindima zazo:

Ipayipi le-PVC:Ipayipi le-polyvinyl chloride (PVC) lingenye yezinto ezisetshenziswa kakhulu zamapayipi futhi lingasetshenziswa emanzini, igesi, indle, ukudluliselwa kwezimboni, njll. Ipayipi le-PVC linokumelana nokugqwala, ukumelana nengcindezi, ukuvalwa okuhle, intengo ephansi, njalo njalo.

Ipayipi le-PE:Ipayipi le-polyethylene (PE) liphinde libe yinto evamile yepayipi, esetshenziswa kakhulu emanzini, igesi, indle, njll. Ipayipi le-PE linokumelana nokushayisana, ukumelana nokugqwala, ukuguquguquka okuhle, njalo njalo.

Ipayipi le-PP-R:Ipayipi le-polypropylene random copolymer (PP-R) lingasetshenziswa ezinhlelweni zamanzi zangaphakathi, ekufudumaleni phansi, efrijini, njll. Ipayipi le-PP-R linokumelana nokushisa okuphezulu, ukumelana ne-asidi, kanye ne-alkali, akulula ukulilinganisa, njalo njalo.

Ipayipi le-ABS:Ipayipi le-ABS liyipayipi elingathinteki, elingagqwali, elisetshenziswa kakhulu ekuhlanzweni kwendle, indle yasekhishini, nakwezinye izindawo.

Ipayipi le-PC:Ipayipi le-polycarbonate (PC) linamandla aphezulu, ukukhanya okuphezulu, nezinye izici, futhi lingasetshenziswa emigwaqweni emikhulu, emihubheni, ezitimeleni ezingaphansi komhlaba, nakwezinye izindawo zokwakha.

Ipayipi le-PA:Ipayipi le-polyamide (PA) lisetshenziswa kakhulu emkhakheni womoya, uwoyela, amanzi, kanye nokunye ukuthuthwa koketshezi. Ipayipi le-PA alikwazi ukugqwala, alikwazi ukumelana nokushisa, alikwazi ukumelana nokucindezela, kanye nezinye izici.

Izinto ezahlukene zamapayipi epulasitiki zifanelekela amasimu ahlukene. Ngokuvamile, amapayipi epulasitiki anezinzuzo zokuba lula, ashibhile, amelana nokugqwala, alungele ukwakhiwa, njll., futhi kancane kancane athatha indawo yamapayipi ensimbi endabuko, futhi adlala indima ebaluleke kakhulu ekwakheni kwesimanje.

Kodwa-ke, ezinye izinkinga ezivamile zingase zihlangane ngesikhathi sokukhiqizwa nokucutshungulwa kwamapayipi epulasitiki, okuhlanganisa:

Ukuncibilika okuncane:Ezinye izinto zokusetshenziswa zepulasitiki enqubweni yokucubungula, ngenxa yesakhiwo se-molecule chain nezinye izici, zingaholela ekuncibilikeni okungekuhle kokuncibilika, okuholela ekugcwalisweni okungalingani enqubweni yokubumba i-extrusion noma i-injection, ikhwalithi yobuso engagculisi, kanye nezinye izinkinga.

Ukuzinza okungekuhle kobukhulu:ezinye zezinto zokusetshenziswa zepulasitiki enqubweni yokucubungula nokupholisa ziyancipha, okuholela kalula ekuzinzeni okungekuhle kobukhulu bomkhiqizo oqediwe, noma ngisho nokuguquguquka nezinye izinkinga.

Ikhwalithi ephansi yobuso:Enkambisweni yokukhipha noma ukubumba ngomjovo, ngenxa yokwakheka okungenangqondo kwezikhunta, ukulawulwa okungafanele kokushisa kokuncibilika, njll., kungaholela ezifweni ezifana nokungalingani, amabhamuza, iminonjana, njll. ebusweni bemikhiqizo eqediwe.

Ukumelana nokushisa okubi:ezinye izinto zokusetshenziswa zepulasitiki zivame ukuthamba futhi ziguquguquke emazingeni okushisa aphezulu, okungaba yinkinga ekusetshenzisweni kwamapayipi okudingeka amelane nezimo zokushisa okuphezulu.

Amandla okuqinela anganele:ezinye izinto zokusetshenziswa zepulasitiki azinawo amandla aphezulu ngokwazo, okwenza kube nzima ukuhlangabezana nezidingo zamandla okunamathela kwezinye izinhlelo zokusebenza zobunjiniyela.

Lezi zinkinga ngokuvamile zingaxazululwa ngokuthuthukisa ukwakheka kwezinto zokusetshenziswa, ukwenza ngcono amasu okucubungula, kanye nokuthuthukisa ukwakheka kwesikhunta. Ngesikhathi esifanayo, kungenzeka futhi ukwengeza ama-ejenti okuqinisa akhethekile, ama-filler, ama-lubricant, nezinye izingxenye ezisizayo ukuze kuthuthukiswe ukusebenza kokucubungula kwamapayipi epulasitiki kanye nekhwalithi yomkhiqizo oqediwe. Sekuyiminyaka eminingi, izinsiza zokucubungula i-PPA (Polymer Processing Additive) fluoropolymer ziye zakhethwa abakhiqizi abaningi bamapayipi njengezithambisi.

Izithasiselo zokucubungula i-PPA (Polymer Processing Additive) ze-fluoropolymer ekukhiqizeni amapayipi zisetshenziswa kakhulu ukuthuthukisa ukusebenza kokucubungula, ukuthuthukisa ikhwalithi yemikhiqizo eqediwe, nokunciphisa izindleko zokukhiqiza. Ngokuvamile zikhona ngesimo sezithambisi, futhi zinganciphisa ngempumelelo ukumelana kokungqubuzana, futhi zithuthukise ukugeleza kokuncibilika nokugcwaliswa kwepulasitiki, ngaleyo ndlela kuthuthukiswe umkhiqizo kanye nekhwalithi yomkhiqizo enqubweni yokubumba noma yokujova.

Emhlabeni jikelele, i-PFAS isetshenziswa kabanzi nasezinhlelweni eziningi zezimboni kanye nabathengi, kodwa izingozi zayo ezingaba khona emvelweni nasempilweni yabantu ziye zabangela ukukhathazeka okukhulu. Njengoba i-European Chemicals Agency (ECHA) yenza imikhawulo ye-PFAS yaziwe ngo-2023, abakhiqizi abaningi sebeqala ukufuna ezinye izindlela zokusebenzisa izinsiza zokucubungula i-PPA fluoropolymer.

Ukusabela ezidingweni zemakethe ngezixazululo ezintsha——Ukuqaliswa kwe-SILIKEUsizo Lokucubungula I-Polymer Yamahhala ye-PFAS (PPAS)

Ukuphendula ukuthambekela kwaleso sikhathi, ithimba le-R&D le-SILIKE litshale umzamo omkhulu ekuthuthukiseniIzinsiza zokucubungula i-polymer ezingenayo i-PFAS (ama-PPA)kusetshenziswa izindlela zobuchwepheshe zakamuva kanye nokucabanga okusha, okwenza umnikelo omuhle ekuvikelweni kwemvelo kanye nentuthuko esimeme.

I-PPA Engenayo i-SILIKE Fluorineigwema izingozi zemvelo nezempilo ezihlobene nama-compounds endabuko e-PFAS ngenkathi iqinisekisa ukusebenza kokucubungula kanye nekhwalithi yezinto ezibonakalayo.I-PPA Engenayo i-SILIKE Fluorineayigcini nje ngokuthobela imikhawulo ye-PFAS eshicilelwe yi-ECHA kodwa futhi inikeza enye indlela ephephile nethembekile kunezakhi ze-PFAS zendabuko.

I-PPA Engenayo i-SILIKE Fluorineiyi-PFAS-free polymer processing aid (PPA) evela ku-SILIKE. Lesi sithako siwumkhiqizo we-polysiloxane oguqulwe ngendlela yemvelo osebenzisa umphumela omuhle kakhulu wokuthambisa we-polysiloxanes kanye ne-polarity yamaqembu aguquliwe ukuze athuthele futhi asebenze emishinini yokucubungula ngesikhathi sokucubungula.

I-PPA Engenayo i-SILIKE Fluorine ingaba yindawo efanele yokusiza ekucubunguleni i-PPA esekelwe ku-fluorine. Ukwengeza inani elincane le-I-SILIKE Fluorine-Free PPA SILIMER 5090,I-SILIMER 5091ingathuthukisa ngempumelelo ukugeleza kwe-resin, ukucutshungulwa, ukuthambisa, kanye nezakhiwo zomphezulu we-extrusion yepulasitiki, iqede ukuphuka kokuncibilika, ithuthukise ukumelana nokuguguleka, inciphise i-coefficient yokungqubuzana, futhi ithuthukise isivuno kanye nekhwalithi yomkhiqizo ngenkathi inobungani nemvelo futhi iphephile.

Indima kaI-SILIKE Fluorine-Free PPA SILIMER 5090ekukhiqizweni kwamapayipi epulasitiki:
