Kodi mphira wa Mlingo wa silikoni umachokera kuti?

 

Kuti mumvetsetse njira zambiri zogwiritsira ntchito mphira wa silicone, ndikofunikira kuzindikira zoyambira zake. Mu blog iyi, tikuwona komwe silicone imachokera kuti timvetse zambiri za makhalidwe ake.

 

Kumvetsetsa mitundu yosiyanasiyana ya rabara

Kuti mumvetse chomwe silicone ndi choyamba muyenera kudziwa mitundu yosiyanasiyana ya mphira yomwe ilipo. Mu mawonekedwe ake oyera, mphira wachilengedwe amadziwika kuti ndi latex ndipo amachokera mwachindunji kumtengo wa rabara. Mitengoyi idapezeka koyamba ku South America ndipo kugwiritsidwa ntchito kwa mphira kuchokera mkati mwake kunayambira ku chikhalidwe cha Olmec (Olmec kwenikweni amatanthauza "Anthu a Rubber"!).

Chilichonse chomwe sichinapangidwe kuchokera ku mphira wachilengedwechi ndichopangidwa ndi anthu ndipo chimadziwika kuti chopangidwa.

Chinthu chatsopano chopangidwa posakaniza zinthu zosiyanasiyana chimatchedwa polymer yopangira. Ngati polima ikuwonetsa zotanuka, imadziwika kuti ndi elastomer.

 

Kodi silicone yopangidwa kuchokera ku chiyani?

Silicone imadziwika kuti ndi elastomer yopangira popeza ndi polima yomwe imawonetsa kukhuthala - kutanthauza kuti imawonetsa kukhuthala komanso kukhazikika. Colloquially anthu amati zotanuka makhalidwe mphira.

Silicone yokha imapangidwa ndi kaboni, haidrojeni, mpweya ndi silicon. Dziwani kuti zomwe zili mkati mwa silicone zimalembedwa mosiyana. Zosakaniza za silicon zimachokera ku silika yomwe imachokera ku mchenga. Njira yopangira silicon ndi yovuta ndipo imaphatikizapo magawo ambiri. Njira yovutayi imathandizira pamtengo wapamwamba wa rabara ya silicone poyerekeza ndi mphira wachilengedwe.

Njira yopanga silikoni imaphatikizapo kuchotsa silicon ku silica ndikudutsa mu ma hydrocarbon. Kenako amasakanizidwa ndi mankhwala ena kuti apange silikoni.

 

Kodi mphira wa silikoni umapangidwa bwanji?

Rabara ya silicone ndi kuphatikiza kwa msana wa Si-O, wokhala ndi magulu ogwirira ntchito ophatikizidwa. Chomangira cha silicon-oksijeni chimapatsa silikoni kukana kwake kutentha kwambiri komanso kusinthasintha kwa kutentha kosiyanasiyana.

Silicone polima imasakanizidwa ndi zolimbitsa zolimbitsa thupi komanso zothandizira kukonza kuti zipange chingamu cholimba, chomwe chimatha kulumikizidwa pa kutentha kokwera pogwiritsa ntchito peroxides kapena polyaddition kuchiritsa. Akalumikizidwa, silikoni imakhala yolimba, ya elastomeric.

Pano ku Silicone Engineering, zida zathu zonse za silikoni zimachiritsidwa pogwiritsa ntchito kutentha komwe kumayika zinthu zathu za silikoni kukhala HTV silicone kapena High Temperature Vulcanised. Magiredi athu onse a silicone amapangidwa, osakanizidwa ndikupangidwa ku 55,000-sq yathu. ft. ku Blackburn, Lancashire. Izi zikutanthauza kuti tili ndi kutsata kwathunthu komanso kuyankha pakupanga ndipo titha kuwonetsetsa kuti pakhale miyezo yapamwamba kwambiri yoyendetsera bwino nthawi zonse. Panopa timapanga matani opitilira 2000 a mphira wa silikoni chaka chilichonse zomwe zimatipangitsa kukhala opikisana kwambiri pamsika wa silikoni.

 

Ubwino wogwiritsa ntchito mphira wa silicone ndi chiyani?

Kapangidwe kake ndi kapangidwe ka mphira wa silikoni kumapangitsa kusinthasintha kwakukulu, zomwe zimapangitsa kuti zikhale zotchuka kwambiri pazogwiritsa ntchito zambiri. Imatha kupirira kusinthasintha kwakukulu kwa kutentha kuyambira -60 ° C mpaka 300 ° C.

Ilinso ndi kukana kwachilengedwe kwa ozoni, UV komanso kupsinjika kwanyengo komwe kumapangitsa kuti ikhale yabwino kusindikiza panja ndikutetezedwa kuzinthu zamagetsi monga kuyatsa ndi zotsekera. Siponji ya silikoni ndi chinthu chopepuka komanso chosunthika chomwe chimapangitsa kuti chichepetse kugwedezeka, kukhazikika m'malo olumikizirana mafupa komanso phokoso lochepera pamaulendo ambiri - kupangitsa kuti ikhale yotchuka kugwiritsidwa ntchito m'malo monga masitima apamtunda ndi ndege komwe chitonthozo chamakasitomala chimathandizidwa ndikugwiritsa ntchito mphira wa silikoni.

Ichi ndi chidule chachidule cha chiyambi cha rabara ya silicone. Komabe, pa JWT Rubber timamvetsetsa kufunikira kwakuti mumvetsetse chilichonse chokhudza zomwe mukugula. Ngati mukufuna kudziwa zambiri kuti mumvetsetse momwe mphira wa silikoni ungagwire ntchito mumakampani anu, lumikizanani nafe lero.
