Intshayelelo:
Ehlabathini lenzululwazi yemathiriyeli kunye nobunjineli, izinto ezintsha zihlala zivela ezithembisa ukuguqula amashishini kunye nokuhlengahlengisa indlela esijongana ngayo noyilo kunye nemveliso. Olunye ulutsha olunjalo luphuhliso kunye nokwamkelwa kwe-dynamic vulcanizate thermoplastic Silicone-based elastomer (ifinyezwa ngokubanzi kwi-Si-TPV), imathiriyeli eguquguqukayo enokuthi ithathe indawo ye-TPE yendabuko, i-TPU, kunye ne-silicone kwizicelo ezahlukeneyo.
I-Si-TPV ibonelela ngomphezulu onesilky ekhethekileyo kunye nokuchukumisa ulusu, ukumelana nokuqokelelwa kokungcola okugqwesileyo, ukumelana nokukrweleka okungcono, ayiqulathanga iplastiki kunye neoyile ethambisayo, akukho mngcipheko ukopha / uncangathi, kwaye akukho vumba, nto leyo eyenza ukuba ibe yenye enomtsalane I-TPE, i-TPU, kunye ne-silicone kwiimeko ezininzi, ukusuka kwiimveliso zabathengi ukuya kwizicelo zamashishini.
Ukumisela xa i-Si-TPVs inokutshintsha ngokufanelekileyo i-TPE, i-TPU, kunye ne-silicone, kufuneka sihlolisise iipropati zabo, izicelo, kunye neenzuzo. Kweli nqaku, Jonga kuqala Ukuqonda i-Si-TPV kunye ne-TPE!
Uhlalutyo lokuthelekisa lwe-TPE kunye ne-Si-TPV
1.I-TPE (i-Thermoplastic Elastomers):
I-TPEs yiklasi yezinto eziguquguqukayo ezidibanisa iimpawu ze-thermoplastics kunye ne-elastomers.
Baziwa ngokuba bhetyebhetye, ukomelela, kunye nokulula ukusetyenzwa.
Ii-TPE zibandakanya iindidi ezahlukahlukeneyo, ezifana ne-TPE-S (i-Styrenic), i-TPE-O (i-Olefinic), kunye ne-TPE-U (i-Urethane), nganye ineempawu ezahlukileyo.
2.I-Si-TPV ( dynamic vulcanizate thermoplastic Silicone-based elastomer ):
I-Si-TPV ngumfaki omtsha kwimarike ye-elastomer, edibanisa inzuzo yerubha ye-silicone kunye ne-thermoplastics.
Ibonelela ngokumelana nobushushu, imitha ye-UV, kunye neekhemikhali, i-Si-TPV inokusetyenzwa kusetyenziswa iindlela eziqhelekileyo ze-thermoplastic ezifana nokubumba inaliti kunye ne-extrusion.
Ingayenza nini i-Si-TPV Eyenye ye-TPE?
1. Izicelo zobushushu obuphezulu
Enye yeenzuzo eziphambili ze-Si-TPV ngaphezulu kwee-TPE ezininzi kukuxhathisa kwayo okungaqhelekanga kumaqondo obushushu aphezulu. Ii-TPE zinokuthamba okanye ziphulukane neempawu zazo ezinwebekayo kumaqondo obushushu aphezulu, zithintele ukufaneleka kwazo kwizicelo apho ukuxhathisa ubushushu kubalulekile. I-Si-TPV kwelinye icala, igcina ukuguquguquka kwayo kunye nemfezeko nakwiqondo lokushisa eligqithileyo, iyenza ibe yindawo efanelekileyo ye-TPE kwizicelo ezifana nezixhobo zemoto, iziphatho ze-cookware, kunye nezixhobo zemizi-mveliso eziphantsi kobushushu.
2. Ukumelana neeKhemikhali
I-Si-TPV ibonisa ukuxhathisa okuphezulu kwiikhemikhali, i-oyile, kunye ne-solvents xa kuthelekiswa neentlobo ezininzi ze-TPE. Oku kuyenza ibe lukhetho olufanelekileyo kwizicelo ezifuna ukuvezwa kwimo engqongileyo yeekhemikhali ezirhabaxa, ezinje ngetywina, iigaskithi, kunye nemibhobho kwisixhobo sokwenza imichiza. Ii-TPE azinakubonelela ngenqanaba elifanayo lokumelana neekhemikhali kwiimeko ezinjalo.
3. Ukuhlala ixesha elide kunye neMozulu
Kwiimeko zendalo zangaphandle kunye nezinzima, i-Si-TPV idlula i-TPE ngokuzinzileyo kunye nobuchule bemozulu. Ukuchasa i-Si-TPV kwimitha ye-UV kunye nemozulu iyenza ibe lukhetho oluthembekileyo kwizicelo zangaphandle, kubandakanya amatywina kunye neegaskithi kulwakhiwo, ezolimo, kunye nezixhobo zaselwandle. Ii-TPE zinokuthoba okanye ziphulukane neempawu zazo xa zibekwe kukukhanya kwelanga ixesha elide kunye nemiba yokusingqongileyo.
4. I-Biocompatibility
Kwizicelo zonyango kunye nokhathalelo lwempilo, i-biocompatibility ibalulekile. Ngelixa eminye imiqulu ye-TPE ihambelana nebhayoloji, i-Si-TPV ibonelela ngendibaniselwano eyodwa ye-biocompatibility kunye nokumelana nobushushu obukhethekileyo, iyenza ibe lukhetho olukhethwayo kumacandelo afana netyhubhu yonyango kunye netywina ezifuna zombini iipropathi.
5. Ukusetyenzwa ngokutsha kunye nokuRisayikilishwa
Indalo ye-Si-TPV ye-thermoplastic ivumela ukusetyenzwa kwakhona nokuphinda kusetyenziswe kwakhona xa kuthelekiswa neeTPEs. Lo mba uhambelana neenjongo zozinzo kunye nokunciphisa inkunkuma yezinto eziphathekayo, okwenza i-Si-TPV ibe yinto ekhangayo kubakhiqizi abajolise ekunciphiseni indawo yabo yokusingqongileyo.
Isiphelo:
Ihlala ingumbono olungileyo ukuphanda kwaye uqinisekise imveliso yentengiso yentengiso yangoku i-Si-TPV xa ukhangela i-TPE!!
Nangona ii-TPE zisetyenziswe ngokubanzi kwizicelo ezahlukeneyo ngenxa yokuguquguquka kwazo. Nangona kunjalo, ukuvela kwe-Si-TPV kwazise enye indlela enyanzelisayo, ngakumbi kwiimeko apho ukumelana nobushushu obuphezulu, ukumelana neekhemikhali, kunye nokuqina kubalulekile. I-Si-TPV's indibaniselwano eyodwa yeepropathi iyenza ibengumbangi onamandla wokubuyisela ii-TPE kumashishini amaninzi, ukusuka kwimizi-mveliso kunye nezoshishino ukuya kukhathalelo lwempilo kunye nosetyenziso lwangaphandle. Njengoko uphando kunye nophuhliso kwinzululwazi yemathiriyeli iqhubela phambili, indima ye-Si-TPV ekuthatheni indawo yee-TPEs kusenokwenzeka ukuba yande, inika abavelisi ukhetho oluninzi lokuphucula iimveliso zabo kwiimfuno ezithile.
