Umahluko kunye neempawu ze TPU, Irabha kunye neSilicone

inkcazelo

TPU Inkcazo:

TPU luhlobo lwe thermoplastic elastomer (TPE), emele i-thermoplastic polyurethane elastomer. Ayinabungozi kokusingqongileyo, ayinatyhefu, kwaye inokuphinda isetyenziswe. TPU inokumelana nokunxiba okugqwesileyo, ukuqina, kunye nokumelana neoyile. Ubunzima bayo buvela kwi-70A ukuya kwi-98A, kwaye umbala wayo wokuqala uyabonakala.

Inkcazo yerabha:

I-Rubber inokwahlulwa ibe yirubha yendalo kunye nerabha yokwenziwa ngokwezinto ezibonakalayo. Irabha yendalo itsalwa kwimithi yerabha, ngelixa irabha yokwenziwa yenziwe ngokufanelekileyo. I-Rubber ineentlobo ezahlukeneyo kunye namaqondo okumelana nokugqoka. I-Rubber yi-polymer e-amorphous ngokupheleleyo, e-elastic kwiqondo lokushisa kwaye inokuvelisa i-deformation enkulu phantsi kwamandla amancinci angaphandle. Emva kokususa amandla angaphandle, inokubuyisela isimo sayo sokuqala.

Silicone Ingcaciso:

I-Silicone sisixhobo se-adsorbent esisebenza kakhulu esinobuhlobo nokusingqongileyo, singenabungozi, kwaye singenavumba. Inokusebenza okuphezulu kwe-adsorption, ayinyibiliki emanzini, inozinzo oluhle lwe-thermal kunye nokuzinza kweekhemikhali, kwaye inamandla amakhulu omatshini.

Umahluko kunye neempawu:

Imvakalelo ye-silicone ithambile, kwaye ukuqina kwayo akulunganga TPU. Ivakala incangathi kwaye kulula ukutsala uthuli, nto leyo eyenza kube nzima ukuyicoca. Ukuphefumla kwayo akunamandla kangako TPU, kwaye xa isetyenziselwa ukwenza iimeko zefowuni kunye nezinye iimeko zokukhusela imveliso ye-elektroniki, inokubangela ukutshatyalaliswa kobushushu obungalunganga kwifowuni. I-Silicone nayo inento engalunganga kuba ukuxhathisa kwayo kweenyembezi kubi kwaye amandla ayo okuqina aphantsi. Inzuzo kuphela kukuba inexabiso eliphantsi kune TPU. TPU Iimeko zefowuni eziphathekayo kunye nezikhuselo ezikhuselayo zoyisa iintsilelo zeemeko zefowuni ze-silicone, ngokuxhathisa okulungileyo kokunxiba, ukuxhathisa ukukrala, ukuxhathisa impembelelo, ukufunxa ukothuka, kunye nokuqina. TPU iimeko zefowuni zinemvakalelo eyomileyo kwaye ekhululekile, musa ukuguga ifowuni, musa ukutsala uthuli, kwaye kulula ukuyicoca, okwenza ukuba zidume phakathi kwabathengi kunye nabavelisi. Xa kuthelekiswa nerabha, TPU ineengenelo ezicacileyo ekuxhathiseni ukunxiba, ukomelela koomatshini, ukunwebeka, kunye nokuqina kobushushu obuphantsi, nangona enye irabha ekwaziyo ukunxiba inokumelana nokunxiba. TPU inokumelana nobushushu obuphantsi kwaye isenakho ukunwebeka okugqwesileyo kunye nokomelela ku -50 ℃, ngelixa irabha ingakwazi kwaye iba brittle kwaye kulula ukuqhawuka. Okwangoku, iimveliso ezininzi kwimarike zenziwe ngerabha ikakhulu ngenxa yokuba inexabiso eliphantsi kwaye inexabiso eliphantsi. Inyaniso, TPU izixhobo zinokuthatha indawo yerabha ekusebenzeni okuninzi. Kwilixa elizayo, TPU iya kuba yenye yezona zinto zithandwa kakhulu kwimveliso.

Ukwahlula njani?

Ke, kwinkqubo yokuvelisa kunye nokusetyenziswa, sahlula njani phakathi TPU, irabha, kunye nesilicone? Siyakwazi ukwahlula ezi zinto zintathu kakuhle ngokutshisa, ukuvumba, ubunzima, njl.

TPU (i-thermoplastic polyurethane):

Idangatye elivuthayo lityheli, kunye nesandi esincinci sokudubula kunye nesiqhushumbisi; inevumba elikhethekileyo (ivumba le-ammonia); TPU ngamasuntswana abonakalayo, kwaye anokudityaniswa nomhlophe okanye omnyama. Uluhlu lobunzima yi-60A ~ 80D.

Irabha (uhlobo oluxhatshaziweyo):

Umlilo ovuthayo uphuzi, kwaye iphunga elivuthayo likhulu (i-hydrocarbons enamakha, i-vulcanizing agents, i-anti-aging agents kunye nezinye izongezo zitshisa ukuvelisa); iimveliso zerabha ezihlanjululweyo zihlala zimnyama, kodwa kunye neemveliso zobisi ezimhlophe okanye ezityheli; ubulukhuni bezinto eziphathekayo ngokuqhelekileyo yi-50 ~ 80A. Iimveliso zerabha zinokomelela okubalaseleyo.

I-Silicone:

Idangatye elivuthayo limhlophe qhwa, linephunga elilula, umsi omncinci, kwaye intsalela ingumgubo omhlophe; i-silicone ineengqungquthela ezicacileyo, kunye nezinye izinto eziqinileyo ezingaqhelekanga; yahlulwe kwi-silicone ye-inorganic kunye ne-organic; uluhlu lobunzima yi-10 ~ 90A. I-Silicone inokomelela okugqwesileyo kokuqina.
