Wai kitea te āhuatanga o te rapa vulcanization, a he aha te mea te reira?

Wai kitea te āhuatanga o te rapa vulcanization, mohio kore katoa. Ahakoa te ingoa o tenei tangata pinepine whakahuatia i roto i te pānuitanga. ko tona ingoa Charles Nelson Goodyear, me tenei ra tona ingoa, "Ko" potae waitohu rongonui. Te kore tona whai wāhi, "rapa Indian" (rapa) kia kore i riro te whakamahi whānui, t. Ki. Ko reira tika he gimmick, kotahi kawea i Amerika. No te tau maha, whakahaere Charles maha ngā ki rerekē wāhanga Mixing rapa (i hinu paina ki paitini waikura konutea), i roto i 1839 e kore e tau whakatuwheratia e te hanganga o te taonga ki te whanariki.

He aha te mea te tukanga vulcanization rapa? Mai i te tirohanga o te matū - he ngāwari rāpoi rapa pūhui i roto i toru-ahu momo mātiti mokowā, me here matū hake e tika onge. Ko te taonga whakamutunga taea potae ki noho te taua tino ngāwari, pehea i reira he rapa maori, kua hanga i nei te reira.

I roto i te rapa vulcanization taea te whiwhi te tukutuku i raro i te pāmahana nui radiation ranei, a hoki ka tono kaihoko matū motuhake. Ka rite ki te tikanga, mo te pokanga whakamahi wae motuhake rite nga kohua i, mīhini werohanga niao, poka, autoclaves, Kukume-vulcanizers me coolants (i te mamaoa wera ki te whakawera hiko).

Ko te pāmahana haamărôraa o rapa raw taea e rawa kanorau i runga i te whakamahi o te hua whakamutunga rānei. Ko i 130 ki te 200 degrees te whānuitanga matarohia, ahakoa coatings rapa me adhesives ētahi wā ora i te pāmahana rūma (i te 20 nekehanga, te "vulcanization makariri"). He tino rerekē mō te tukanga i homai matū āpiha. Nuinga o ngā wā kawea vulcanization pungatara, e taea ana ki te farii i te rubbers diene whakamahia i roto i te tupare ki ahumahi me hu rapa. I tua atu, te takaro he wāhi nui e te pera-ka karanga "boosters" (mo te momo o muri o te tukanga), he te nuinga reira sulfonamides ka whakakapia TIZOL.

kia whakahaere vulcanization Hot o rapa i roto i te wa poto rawa ki te whai wāhi i te boosters i roto i te tukanga matū: dithiocarbamates, xanthates ranei. I roto i tenei take e te mahi wahi tere i te pāmahana o e pā ana ki 110-125 nekehanga. Hoki te whakaora i nga adhesives me etahi taherapa nunumi pāmahana o raro (20 ki te 100 nekehanga) Ka taea te whakamahi i te whakamahi i te konutai dimethyldithiocarbamate.

Whakamahia i roto i te vulcanization o matū pŭpŭ tauturu rapa (oligoester acrylates, peroxides, phenol kapia, me ētahi atu) Tukua ki te tiki hua ki ātete wera nui, nukurau, ake āhuatanga uruhanga. Ko ano hoki te reira i kore te tūnga whakamutunga i roto i te hanganga o te hua (i te kapu o putu ki whakapaipai), antioxidants (tākaro roa te ora rapa) me plasticizers, tuku ki te whakaiti i te pokey o te taonga i roto i te maimoatanga, me te tere o ", kōmuru".
