Intshayelelo:
Kwihlabathi lesayensi yezinto kunye nobunjineli, izinto ezintsha zihlala zivela ezithembisa ukuguqula amashishini kwaye zitshintshe indlela esijongana ngayo noyilo kunye nemveliso. Enye yezo zinto ezintsha kukuphuhliswa kunye nokwamkelwa kwe-dynamic vulcanizate thermoplastic Silicone-based elastomer (efinyezwa ngokubanzi kwi-Si-TPV), into eguquguqukayo enokukwazi ukuthatha indawo ye-TPE yendabuko, i-TPU, kunye ne-silicone kwizicelo ezahlukeneyo.
I-Si-TPV inika umphezulu onomphezulu othambileyo nothambileyo, okwaziyo ukumelana nokuqokelelwa kokungcola, okwaziyo ukumelana nokukrwela, ongenayo i-plasticizer kunye neoyile ethambileyo, ongakwaziyo ukopha/ukunamathela, kwaye ongenayo ivumba elimnandi, nto leyo eyenza ukuba ibe yindlela enomtsalane endaweni ye-TPE, TPU, kunye ne-silicone kwiimeko ezininzi, ukusuka kwiimveliso zabathengi ukuya kwizicelo zoshishino.
Ukuze sifumanise ukuba ii-Si-TPV zinokuthatha indawo ye-TPE, i-TPU, kunye ne-silicone ngokufanelekileyo nini, kufuneka sihlolisise iipropati zazo, usetyenziso kunye neenzuzo. Kweli nqaku, jonga kuqala Ukuqonda i-Si-TPV kunye ne-TPE!
Uhlalutyo oluthelekisayo lwe-TPE kunye ne-Si-TPV
1.I-TPE (ii-Thermoplastic Elastomers):
IiTPE luhlobo lwezinto eziguquguqukayo ezidibanisa iipropati ze-thermoplastics kunye nee-elastomers.
Ziyaziwa ngokuguquguquka kwazo, ukuqina kwazo, kunye nokulula kwazo ukucutshungulwa.
Ii-TPE ziquka iintlobo ezahlukeneyo, ezifana ne-TPE-S (Styrenic), i-TPE-O (Olefinic), kunye ne-TPE-U (Urethane), nganye ineempawu zayo ezahlukeneyo.
2.I-Si-TPV (i-dynamic vulcanizate thermoplastic Silicone-based elastomer):
I-Si-TPV yeyona intsha kwimarike ye-elastomer, idibanisa iingenelo zerabha ye-silicone kunye ne-thermoplastics.
Inika ukumelana okuhle kakhulu nobushushu, imitha ye-UV, kunye neekhemikhali, i-Si-TPV ingacutshungulwa kusetyenziswa iindlela eziqhelekileyo ze-thermoplastic ezifana nokubumba ngenaliti kunye nokukhupha.
I-Si-TPV Alternative TPE ingenziwa nini?
1. Izicelo zoBushushu obuPhezulu
Enye yezona nzuzo ziphambili zeSi-TPV kunee-TPE ezininzi kukumelana kwayo okungaqhelekanga namaqondo obushushu aphezulu. Ii-TPE zinokuthambisa okanye zilahlekelwe ziimpawu zazo zokunwebeka kumaqondo obushushu aphezulu, nto leyo ethintela ukufaneleka kwazo kwiindawo apho ukumelana nobushushu kubalulekile khona. Kwelinye icala, iSi-TPV igcina ukuguquguquka kwayo kunye nokuthembeka kwayo nokuba kumaqondo obushushu aphezulu, nto leyo eyenza ukuba ibe yindawo efanelekileyo yokutshintsha i-TPE kwiindawo ezifana nezixhobo zeemoto, iziphatho zezixhobo zokupheka, kunye nezixhobo zoshishino ezifudunyezwa bubushushu.
2. Ukumelana neekhemikhali
I-Si-TPV ibonakalisa ukumelana okuphezulu kwiikhemikhali, iioyile, kunye nezinyibilikisi xa kuthelekiswa nezinye iintlobo ezininzi ze-TPE. Oku kwenza ukuba ibe lukhetho olufanelekileyo kwizicelo ezifuna ukuvezwa kwiindawo ezinobungozi zeekhemikhali, ezifana nezitywino, ii-gasket, kunye neepayipi kwizixhobo zokucubungula iikhemikhali. Ii-TPE zisenokungaboneleli ngenqanaba elifanayo lokuxhathisa iikhemikhali kwiimeko ezinjalo.
3. Ukuqina kunye nokuVuselela iMozulu
Kwiimeko zokusingqongileyo zangaphandle nezinzima, i-Si-TPV iyazigqitha ii-TPE ngokubhekiselele ekuqineni nasekukwazini kwayo ukumelana nemozulu. Ukuxhathisa kwe-Si-TPV kwimitha ye-UV kunye nokuguquguquka kwemozulu kwenza ukuba ibe lukhetho oluthembekileyo lokusetyenziswa ngaphandle, kubandakanya izitywini kunye nee-gaskets ekwakheni, kwezolimo, nakwizixhobo zaselwandle. Ii-TPE zinokonakala okanye zilahlekelwe ziipropati zazo xa zichatshazelwa kukukhanya kwelanga ixesha elide kunye neemeko zokusingqongileyo.
4. Ukuhambelana kwezinto eziphilayo
Kwizicelo zonyango kunye nokhathalelo lwempilo, ukuhambelana kwezinto eziphilayo kubalulekile. Nangona ezinye iifomyula ze-TPE zihambelana nezinto eziphilayo, i-Si-TPV inikezela ngokudibanisa okwahlukileyo kokuhambelana kwezinto eziphilayo kunye nokumelana nobushushu obugqwesileyo, okwenza kube lukhetho olukhethwayo kwizinto ezifana neetyhubhu zonyango kunye nezitywini ezifuna zombini iimpawu.
5. Ukuphinda Usebenzise kunye Nokuphinda Usebenzise
Uhlobo lwe-thermoplastic ye-Si-TPV luvumela ukuba kube lula ukuphinda kusetyenziswe kunye nokurisayikilisha xa kuthelekiswa nee-TPE. Olu candelo luhambelana neenjongo zozinzo kwaye lunciphisa inkunkuma yezinto ezibonakalayo, nto leyo eyenza i-Si-TPV ibe lukhetho olunomtsalane kubavelisi abajonge ukunciphisa umngcipheko wabo kwindalo esingqongileyo.
Isiphelo:
Kusoloko kuyinto elungileyo ukuphanda nokuqinisekisa imveliso yeSi-TPV ethengiswayo kwimarike yangoku xa ufuna i-TPE!!
Nangona ii-TPE zisetyenziswa kakhulu kwizicelo ezahlukeneyo ngenxa yokuguquguquka kwazo. Nangona kunjalo, ukuvela kwe-Si-TPV kuye kwazisa enye indlela enomtsalane, ngakumbi kwiimeko apho ukumelana nobushushu obuphezulu, ukumelana neekhemikhali, kunye nokuqina kubalulekile. Indibaniselwano eyahlukileyo yeempawu ze-Si-TPV yenza kube ngumchasi onamandla wokutshintsha ii-TPE kwimizi-mveliso emininzi, ukusuka kwiimoto nakwimizi-mveliso ukuya kwizicelo zonyango kunye nezangaphandle. Njengoko uphando nophuhliso kwisayensi yezinto ziqhubeka zihambela phambili, indima ye-Si-TPV ekutshintsheni ii-TPE kusenokwenzeka ukuba yande, inike abavelisi ukhetho oluninzi lokuphucula iimveliso zabo kwiimfuno ezithile.
