Isingeniso:
Ezweni lesayensi yezinto zokwakha kanye nobunjiniyela, izinto ezintsha zivame ukuvela ezithembisa ukuguqula izimboni futhi zishintshe indlela esibheka ngayo ukuklama nokukhiqiza. Enye into entsha enjalo ukuthuthukiswa nokwamukelwa kwe-dynamic vulcanizate thermoplastic Silicone-based elastomer (ngokuvamile efushaniswe ibe yi-Si-TPV), into eguquguqukayo enamandla okufaka esikhundleni se-TPE, i-TPU, kanye ne-silicone yendabuko ezinhlelweni ezahlukahlukene.
I-Si-TPV inikeza indawo enokuthambekela okuhlukile kosilika nokulungele isikhumba, ukumelana okuhle kakhulu nokuqoqwa kokungcola, ukumelana okungcono kokuklwebheka, ayinawo upulasitiki kanye namafutha okuthambisa, ayinangozi yokopha/ukunamathela, futhi ayinaphunga, okwenza kube yindlela ekhangayo esikhundleni se-TPE, i-TPU, kanye ne-silicone ezimweni eziningi, kusukela emikhiqizweni yabathengi kuya ekusetshenzisweni kwezimboni.
Ukuze sinqume ukuthi ama-Si-TPV angayishintsha nini ngempumelelo i-TPE, i-TPU, kanye ne-silicone, sidinga ukuhlola izakhiwo zawo, izinhlelo zokusebenza, kanye nezinzuzo. Kulesi sihloko, bheka kuqala Ukuqonda i-Si-TPV kanye ne-TPE!
Ukuhlaziywa Okuqhathanisayo kwe-TPE kanye ne-Si-TPV
1.I-TPE (i-Thermoplastic Elastomers):
Ama-TPE ayiklasi lezinto eziguquguqukayo ezihlanganisa izakhiwo ze-thermoplastics kanye nama-elastomers.
Baziwa ngokuguquguquka kwabo, ukuqina, kanye nokulula kokucutshungulwa.
Ama-TPE afaka izinhlobo ezahlukene, njenge-TPE-S (Styrenic), i-TPE-O (Olefinic), kanye ne-TPE-U (Urethane), ngayinye inezakhiwo ezihlukile.
2.I-Si-TPV (i-dynamic vulcanizate thermoplastic Silicone-based elastomer):
I-Si-TPV isanda kungena emakethe ye-elastomer, ihlanganisa izinzuzo zerabha ye-silicone kanye ne-thermoplastics.
Inikeza ukumelana okuhle kakhulu nokushisa, imisebe ye-UV, kanye namakhemikhali, i-Si-TPV ingacutshungulwa kusetshenziswa izindlela ezijwayelekile ze-thermoplastic ezifana nokubumba nge-injection kanye ne-extrusion.
I-Si-TPV Alternative TPE ingenziwa nini?
1. Izicelo Zokushisa Okuphezulu
Enye yezinzuzo eziyinhloko ze-Si-TPV kunezinhlobo eziningi ze-TPE ukumelana kwayo okungavamile namazinga okushisa aphezulu. Ama-TPE angathambisa noma alahlekelwe yizakhiwo zawo zokunwebeka emazingeni okushisa aphezulu, okunciphisa ukufaneleka kwawo ekusetshenzisweni lapho ukumelana nokushisa kubalulekile khona. Ngakolunye uhlangothi, i-Si-TPV igcina ukuguquguquka kwayo kanye nobuqotho ngisho nasemazingeni okushisa aphezulu, okwenza kube indawo efanelekile ye-TPE ezisetshenziswayo njengezingxenye zezimoto, izibambo zokupheka, kanye nemishini yezimboni eshiswayo.
2. Ukumelana namakhemikhali
I-Si-TPV ikhombisa ukumelana okuphezulu kwamakhemikhali, uwoyela, kanye nezinyibilikisi uma kuqhathaniswa nezinhlobo eziningi ze-TPE. Lokhu kwenza kube ukukhetha okufanele kwezicelo ezidinga ukuchayeka ezindaweni zamakhemikhali ezinzima, njengezivalo, ama-gasket, namapayipi emishinini yokucubungula amakhemikhali. Ama-TPE angase anganikeli izinga elifanayo lokumelana kwamakhemikhali ezimweni ezinjalo.
3. Ukuqina kanye Nokusimama Kwesimo Sezulu
Ezimweni zemvelo zangaphandle nezinzima, i-Si-TPV idlula ama-TPE ngokuya ngokuqina kanye nekhono lesimo sezulu. Ukumelana kwe-Si-TPV emisebeni ye-UV kanye nesimo sezulu kwenza kube ukukhetha okuthembekile kokusetshenziswa kwangaphandle, okuhlanganisa izivalo nama-gasket ekwakheni, kwezolimo, kanye nemishini yasolwandle. Ama-TPE angase alahle noma alahlekelwe yizakhiwo zawo lapho evezwa elangeni elihlala isikhathi eside kanye nezici zemvelo.
4. Ukuhambisana kwezinto eziphilayo
Ngezicelo zezokwelapha nezokunakekelwa kwempilo, ukuhambisana kwezinto eziphilayo kubalulekile. Nakuba ezinye izinhlobo ze-TPE zihambisana nezinto eziphilayo, i-Si-TPV inikeza inhlanganisela eyingqayizivele yokuhambisana kwezinto eziphilayo kanye nokumelana nokushisa okumangalisayo, okwenza kube ukukhetha okuthandwayo kwezingxenye ezifana namapayipi ezokwelapha kanye nezivalo ezidinga zombili lezi zakhiwo.
5. Ukucubungula Kabusha Nokusebenzisa Kabusha
Imvelo ye-thermoplastic ye-Si-TPV ivumela ukucubungula kabusha nokuvuselela okulula uma kuqhathaniswa nama-TPE. Lesi sici sihambisana nemigomo yokusimama futhi sinciphisa imfucuza yezinto ezibonakalayo, okwenza i-Si-TPV ibe ukukhetha okukhangayo kwabakhiqizi abahlose ukunciphisa ukuthinteka kwabo kwemvelo.
Isiphetho:
Kuhlale kungumqondo omuhle ukucwaninga nokuqinisekisa umkhiqizo we-Si-TPV otholakala emakethe njengamanje uma ufuna i-TPE!!
Nakuba ama-TPE esetshenziswe kabanzi ezinhlotsheni ezahlukene zokusebenza ngenxa yokuguquguquka kwawo. Kodwa-ke, ukuvela kwe-Si-TPV kwethule enye indlela ekhangayo, ikakhulukazi ezimweni lapho ukumelana nokushisa okuphezulu, ukumelana namakhemikhali, kanye nokuqina kubalulekile. Inhlanganisela eyingqayizivele yezakhiwo ze-Si-TPV yenza kube ngumncintiswano onamandla wokufaka esikhundleni sama-TPE ezimbonini eziningi, kusukela kwezezimoto nezimboni kuya kwezezempilo kanye nezicelo zangaphandle. Njengoba ucwaningo nentuthuko kwisayensi yezinto zokwakha luqhubeka nokuthuthuka, indima ye-Si-TPV ekufakeni esikhundleni ama-TPE cishe izokhula, inikeze abakhiqizi izinketho eziningi zokuthuthukisa imikhiqizo yabo ngezidingo ezithile.
