Chingwe cha moyo wautali wazaka 70ndiyoyenera malo onse okhala ndi anthu ochuluka, monga malo ogulitsira, malo owonetsera zisudzo, masiteshoni, ma eyapoti ndi malo ena onse, komanso mizere yofunika yogawa, mawaya omangira, zokongoletsera kunyumba, ndi zina zambiri.
Moyo wautumiki wa mankhwalawa ndi osachepera zaka 70 pa kutentha kwapakati pa 70 ° C.Kutentha kovomerezeka kwa nthawi yayitali kwa woyendetsa chingwe ndi 90 ° C, 105 ° C, ndi 125 ° C;kutentha kwakukulu kwa ntchito panthawi yochepa (nthawi yochuluka ya 5S) ndi 250 ° C.
Chingwe chojambulira chingwe chimatengera mawonekedwe olumikizira ma radiation olumikizana ndi magawo awiri.Kusungunula kwamkati kumakumana ndi ntchito yamagetsi yamagetsi, kusungunula kwakunja kumakumana ndi ntchito yolepheretsa moto, ndipo zigawo zamkati ndi zakunja nthawi imodzi zimakumana ndi moyo wapamwamba.
Zifukwa ndi ubwino wogwiritsa ntchito ma radiation cross-linking pakutchinjiriza (poyerekeza ndi PVC wamba): Zachikhalidwe za PVC sizikhala ndi kukhazikika kwamafuta.
Zimakhala zolimba komanso zowonongeka pa kutentha kochepa, ndipo zimafewetsa mosavuta ndi kumasuka pa kutentha kwakukulu.Imakhala ndi kukana kopanda mphamvu komanso kukana kukalamba, imatulutsa mosavuta mpweya woipa pa kutentha kwakukulu, ndipo imagwetsa mosavuta zinthu zovulaza panthawi yopanga ndikugwiritsa ntchito, zomwe zimapangitsa kuti pakhale zovuta kwa anthu ndi chilengedwe.
Kulumikizana kwa ma radiation kumagwiritsa ntchito matabwa amphamvu kwambiri a ma elekitironi opangidwa ndi ma accelerator a ma elekitironi kuti asinthe mawonekedwe oyambira ngati tcheni kukhala ma cell adimensional network atatu kuti apange maulalo olumikizirana.
Mapangidwe a ma molekyulu atatu-dimensional network ali ndi kukhazikika kwamafuta abwino, ndipo kutsekemera, magetsi ndi makina amawongoleredwa bwino.Kusintha kwakukulu.
Ubwino waukulu wa magwiridwe antchito ndi awa
Moyo wa chingwe umalumikizidwa ndi nyumbayi: zaka 70.Chifukwa cha kukana kutentha kwapamwamba komanso kutentha kwakukulu kwa kutentha kwa kutentha kwa mpweya wozungulira, moyo wautumiki wa chingwe chomwe chimatulutsa kutentha panthawi yogwiritsira ntchito chimakulitsidwa.
Kutha kunyamula kwakukulu: chingwe cholumikizidwa ndi waya chimawonjezeka kuchoka pa 70 ° C mpaka 90 ° C, 105 ° C, ndi 125 ° C.
Kukaniza kwakukulu kwa kutchinjiriza: Popeza kuphatikizika kwa ma radiation kumapewa kugwiritsa ntchito hydroxide ngati choletsa moto, kumalepheretsa kulumikizana kusanachitike panthawi yolumikizana komanso kuchepa kwa kukana kwa insulation chifukwa cha kuyamwa kwa chinyezi mumlengalenga ndi wosanjikiza.Izi zimatsimikizira kukana kwa insulation.
Ubwino wazinthu zokhazikika: Ubwino wa zingwe zachikhalidwe za silane zolumikizidwa (zomwe zimadziwika kuti zingwe zamadzi ofunda) zimakhudzidwa ndi kutentha kwa madzi, njira yotulutsira, zowonjezera zolumikizirana ndi zinthu zina, ndipo mawonekedwe ake ndi osakhazikika, pomwe mtundu wa waya wamtanda. -zingwe zolumikizidwa zimadalira mtengo wa elekitironi.Mlingo wa radiation umayendetsedwa ndi makompyuta, zomwe zimachepetsa zinthu zaumunthu, kotero kuti khalidweli ndi lokhazikika.
Chowotcha moto kwambiri: Zida zowotcha kwambiri zimagwiritsidwa ntchito, ndipo ZA, ZB, ZC, ndi zingwe zitha kupangidwa malinga ndi zosowa zamakasitomala.Ntchito yoletsa moto yadutsa mayeso oyatsa omwe afotokozedwa mu GB/T 1966-2005.
Zopanda halogen, kawopsedwe kakang'ono, utsi wochepa: mawaya amtundu woyamba osagwira ntchito ndi mawaya osayatsa moto sachepera 80%, komanso mawaya ena ocheperako akamayaka sipang'ono. kuposa 60%.The acidity PH mtengo wa mpweya kuyaka si kuchepera 4.3, ndipo madutsidwe sadzakhala wamkulu kuposa 10us/mm.
