HDPE utomoni pawiri-khoma malata chitoliro,
HDPE utomoni wa m'munsi, HDPE utomoni wa mavuvu awiri khoma,

Chifukwa cha ntchito yabwino ya HDPE iwiri-khoma malata chitoliro, ndi chitukuko mofulumira anthu, pang'onopang'ono m'malo chitoliro chikhalidwe, kubweretsa yabwino kwambiri moyo wa anthu.Izi zili choncho chifukwa chitoliro cha malata cha HDPE ndi chotetezeka komanso chosavuta kuposa chitoliro chachitsulo chachikhalidwe ndi chitoliro cha konkire m'mbali zambiri, ndipo imalandiridwanso ndi ntchito zomanga ndipo imagwiritsidwa ntchito mochulukirachulukira m'mapulojekiti osiyanasiyana a mapaipi.

Lero, tiyeni tifotokoze mwatsatanetsatane ubwino wa HDPE-wall-wall bellows ili nawo?

1. HDPE iwiri-khoma malata chitoliro ali amphamvu compressive kukana.hdpe mvuvu ziwiri zamakhoma zimakhala ndi mphamvu zopondereza kuposa mavuvu achikhalidwe pansi pamikhalidwe yofanana.Chifukwa cha mawonekedwe ake apadera, khoma lake lakunja ndi lamalata, lomwe likhoza kuwonjezera kuuma kwa mphete ya chitoliro, kukupatsani kukana mwamphamvu kukakamiza kunja.

2, chitoliro chamalata cha HDPE chokhala ndi khoma lawiri chimakhala ndi ntchito yotsika mtengo.Pansi pa katundu womwewo, chitoliro chamalata cha HDPE chapawiri chimangofunika kukwaniritsa khoma la chitoliro chocheperako, zopangira zokha za mapaipi ena zingagwiritsidwe ntchito, poyerekeza ndi mtengo wa ndalama zaumisiri.Ichi ndi chimodzi mwa zifukwa zomwe mapulojekiti ambiri masiku ano amasankha.

3, HDPE yokhala ndi mivungu iwiri yomanga liwiro imathamanga.Chifukwa cha khoma lopyapyala la HDPE mvuto ziwiri zamakhoma, pakumanga, kaya ndikutsitsa ndikutsitsa kapena kulumikiza, ndikosavuta kuposa mapaipi achikhalidwe, ndipo kukonza pambuyo pake kumakhala kosavuta.Ngati ili pamalo omangidwa mwankhanza, imatha kuwonetsa zabwino za HDPE yokhala ndi mipanda iwiri.

Izi ndi katundu wa HDPE mivumbi iwiri-mipanda, chifukwa ndi mankhwala kwa kupanga chitoliro pulasitiki, ali kusinthasintha wabwino, ndi katundu chilengedwe, choncho, angagwiritsidwe ntchito kwambiri uinjiniya mapaipi.

Kalasi ya chitoliro cha HDPE ili ndi kugawa kwakukulu kapena kugawanika kwa ma molekyulu.Imakhala ndi kukana kolimba kwamphamvu komanso kukhazikika bwino kwa kuuma komanso kulimba.Ndi yolimba kwambiri ndipo imakhala ndi sag yochepa pamene ikukonzedwa.Mapaipi opangidwa pogwiritsa ntchito utomoni uwu amakhala ndi mphamvu zabwino, zolimba komanso zolimba komanso zolimba za SCG ndi RCP..

Utoto uyenera kusungidwa m'nyumba yosungiramo madzi, youma komanso kutali ndi moto ndi dzuwa.Asamawunjikane panja.Panthawi yoyendetsa, zinthuzo zisawonongeke ndi dzuwa lamphamvu kapena mvula ndipo siziyenera kunyamulidwa pamodzi ndi mchenga, nthaka, zitsulo, malasha kapena galasi.Kuyendera limodzi ndi zinthu zapoizoni, zowononga komanso zoyaka moto ndizoletsedwa.

Kugwiritsa ntchito

HDPE chitoliro kalasi angagwiritsidwe ntchito kupanga mipope kuthamanga, monga mapaipi amadzi opsinjidwa, mapaipi gasi mafuta ndi mapaipi ena mafakitale.Itha kugwiritsidwanso ntchito popanga mapaipi osaponderezedwa monga mapaipi okhala ndi malata apawiri, mapaipi omangira makhoma, mapaipi a silicon-core, mapaipi amthirira waulimi ndi mapaipi apawiri a aluminiumplastics.Kuonjezera apo, kudzera mu extrusion yogwira ntchito (silane cross-linking), itha kugwiritsidwa ntchito popanga mapaipi ophatikizika a polyethylene (PEX) popereka madzi ozizira ndi otentha.
