Kana iwe uchitsvaga yakasimba, inogara kwenguva refu yepurojekiti yako inotevera, unogona kunge uchinetseka kana silicone rabha kana tpe iriyo sarudzo chaiyo. Zvishandiso zvese zvine zvazvinobatsira uye zvinokanganisa, saka zvakakosha kuyera sarudzo dzako nemazvo usati waita sarudzo. Heino mhedziso yekukurumidza yechinhu chimwe nechimwe kuti ikubatsire kuita sarudzo ine ruzivo.
Chii chinonzi silicone rabha uye TPE?
Silicone rabha uye TPE ese ari maviri elastomers, zvichireva kuti irabha-senge zvinhu zvinogona kuumbwa nekuumbwa. Iwo ese ari maviri anoshandiswa muakasiyana maapplication, kubva kukubika kubika kusvika kumakesi efoni kusvika kumidziyo yekurapa.
Saka, ndeupi musiyano uripo pakati pesilicone rabha uye TPE? Silicone rabha inogadzirwa nesilicone, yakagadzirwa polymer. TPE inogadzirwa ne thermoplastic elastomers, ari musanganiswa wemapurasitiki nemarabha.
Ndeupi misiyano yakakosha pakati pesilicone rabha uye TPE?
Pane akati wandei misiyano yakakosha pakati pesilicone rubha uye TPE. Silicone rabha irabha rekugadzira rakagadzirwa kubva kusilicone, nepo TPE iri thermoplastic elastomer. Silicone rabha ine yakanaka kupisa kupisa uye kuramba kwemamiriro ekunze, nepo TPE haina. Silicone rabha zvakare inowanzo kudhura kupfuura TPE.
Ndezvipi zvakanakira uye kuipa kwesilicone rubber?
Kune akawanda akasiyana marudzi epolymer zvinhu zviripo pamusika nhasi, imwe neimwe iine yayo yakasarudzika seti yezvivakwa uye mashandisiro. Zviviri zvezvinhu zvinonyanya kufarirwa zvinoshandiswa mumaindasitiri akasiyana siyana isilicone rabha uye thermoplastic elastomers (TPE). Kuti uone kuti ndechipi chinyorwa chinonyatsokodzera zvaunoda, zvakakosha kuti unzwisise misiyano yakakosha pakati pemapolymer maviri aya.
Silicone rabha is inorganic synthetic rabha inoumbwa nesilicone maatomu nemaatomu eokisijeni. Ichi chinyorwa chinozivikanwa nekuramba kutonhora kwakanyanya, UV mwenje, ozone, uye oxygen. Pamusoro pezvo, silicone rabha ine yakanakisa kuramba kumvura uye unyoro, ichiita kuti ive yakakodzera kushandiswa mumashandisirwo uko kusangana nemvura kungangoita. Imwe yakaderera kune silicone rabha ndeyekuti inogona kudhura kana ichienzaniswa nemamwe mapolymer.
Thermoplastic elastomers (TPE) ikirasi yezvigadzirwa zvecopolymer zvinoratidzira zvese zviri zviviri thermoplastic uye elastomeric zvivakwa. MaTPE anogona kuumbwa uye kuumbwa senge thermoplastics, asi iwo ane elasticity yemarabha. Izvi zvinoita kuti TPEs ive sarudzo yakanaka kune maapplication ayo anoda zvese kuchinjika uye kusimba. MaTPE anowanikwa munzvimbo dzakasiyana-siyana dzekuoma kwemazinga, achiita kuti ave akakodzera kune zvese kubva kune zvinyoro zvinyoro kusvika kune dzakaoma-shell makesi. Nekudaro, maTPE anogona kunetsa kudzokorodza nekuda kwehunhu hwawo hwakasanganiswa.
Ndezvipi zvakanakira uye zvakaipira zveTPE?
TPE ikirasi ye thermoplastic elastomers ine zvese rabha uye epurasitiki zvivakwa. Zvigadzirwa zveTPE zvine zvakawanda zvakanaka pamusoro pezvigadzirwa zverabha zvechinyakare. Iyo inowanzogara yakasimba, nekunyanya kubvarura uye kusagadzikana kweabrasion. Ivo zvakare vanoramba akawanda maoiri, makemikari, UV mwenje uye yakanyanya tembiricha inochinja zvirinani pane rabha. MaTPE anonyunguduka uye kuyerera kunge epurasitiki, saka anogona kuumbwa kana kuburitswa muhurefu hunoramba huchiitwa senge rubber tubing. Uye, serabha, TPEs dzinogona kuumbwa kuita chero chimiro chaungafungidzira.
Iyo yakanyanya kusarudzika yeTPEs kudzika kwavo kwekushisa kugadzikana kana ichienzaniswa nemamwe elastomers. Dzinogona kuita brittle pakudziya kwakadzika uye dzinogona kuderera pakupisa kwakanyanya. Aya tembiricha akanyanyisa anogona kukonzera kuti zvikamu zvitenderere kana kukanganisa.
Ndeipi iyo silicone rabha ndiyo yakanakisa sarudzo?
Kunyangwe zvese TPE nesilicone rabha iri sarudzo dzakanakisa dzeakasiyana maapplication, pane mamwe mamiriro apo silicone rabha ndiyo iri nani sarudzo.
Kana iwe uchida chinhu chinogona kumira kutonhora kwakanyanya, ipapo silicone rubber ndiyo nzira yekuenda nayo. Inogona kumira tembiricha inosvika 400 madhigirii Celsius, ichiita kuti ive yakanaka kune maapplication uko kupikisa kupisa kwakakosha.
Uye zvakare, silicone rabha ine yakanakisa kuramba kune UV mwenje uye ozone, zvichiita kuti ive sarudzo yakanaka yekunze kwekushandisa. Chekupedzisira, silicone rabha ine yakakura yemagetsi insulating zvivakwa, zvichiita kuti ive yakakodzera kushandiswa mukati zvikamu zvemagetsi uye mapepa emidziyo.
Ndeipi TPE sarudzo yakanaka?
TPE inopa akati wandei mabhenefiti pamusoro pesilicone rubber, kusanganisira:
-Kuramba kurinani kune UV uye ozonation
-Kukuru kuchinjika uye elasticity
-Zvirinani abrasion kuramba
- Mutengo wakaderera
Nekudaro, pane zvakare zvimwe zvazvakaipira kushandisa TPE, kusanganisira:
– Simba rekubvarura rakaderera
- Kusagadzikana kunopesana nekupisa kwakanyanya
-Kusarudzwa kwemavara mashoma
Ungasarudza sei pakati pesilicone rabha uye TPE?
Kana iwe uchida yakasimba, inodzivirira kupisa zvinhu zvepurojekiti yako, unogona kunge uchinetseka kuti woshandisa silicone rabha kana TPE (thermoplastic elastomer). Zvese zviri zviviri zvinhu zvine zvazvakanakira nezvazvakaipira, saka zvakakosha kuti usarudze chakakodzera pane zvaunoda.
Hezvino zvimwe zvinhu zvekufunga nezvazvo pakuita sarudzo yako:
- Ndeipi tembiricha yeprojekti yako?
- Unoda rudzii rwema mechanical properties?
- Ndeipi nhanho yekurwisa makemikari yaunoda?
- Unoda rudzii rwekunaka?
mhedziso
Silicone rabha ine akawanda mabhenefiti anoita kuti ive yakanaka kune akasiyana maapplication. Inonyatsoenderana nemuviri wemunhu pane zvimwe zvinhu, zvichiita kuti ive yakakodzera kune zvekurapa machubhu. Inopesanawo nekupisa kwepamusoro, zvichiita kuti ive yakakodzera kushandiswa munzvimbo dzepamusoro-soro. Nekudaro, silicone rabha haina kusimba seTPE uye inogona kunge isina kukodzera kune maapplication anoda hupenyu hurefu.
