Mapaipi Apamwamba a PPH & Zopangira 1/2-8 - 3 Way & Equal Tee

Q. Kodi zinthu za PPH ndi chiyani
1. Homopolymer polypropylene zakuthupi
PPH ndi chinthu chopangidwa ndi homopolymer polypropylene chosinthidwa ndi β, chomwe chimakhala ndi kukana kwamphamvu kwamankhwala, kukana kutentha kwambiri, kukana kukhudzidwa, komanso kukana bwino kukwawa. PPH (Polypropylene Homeo) zakuthupi, zomwe zimadziwikanso kuti homo polypropylene, zili ndi mawonekedwe a yunifolomu komanso osakhwima a beta crystal kudzera pakusintha kwa β, komwe kumawonetsa kukana kwa dzimbiri kwamankhwala, kukana abrasion, kukana kutentha kwambiri, kukana dzimbiri, kukana kukalamba komanso kutchinjiriza bwino. Izi sizimagwiritsidwa ntchito kwambiri m'mafakitale monga uinjiniya wamankhwala, zamagetsi, mafakitale opanga mankhwala, komanso kuchiritsa madzi otayira, komanso zimakhala ndi ntchito zambiri m'magawo ambiri chifukwa cha mawonekedwe ake apadera akuthupi ndi mankhwala. Mapaipi ndi mbale za PPH zimapangidwa kukhala zida zolimbana ndi dzimbiri ndipo zimagwiritsidwa ntchito kwambiri m'magawo monga engineering yamankhwala, zitsulo, ndi zamagetsi, kutsimikizira kuti amagwira ntchito bwino komanso kufunikira kogwiritsa ntchito kwambiri.

2.Makhalidwe akuluakulu a zinthu za PPH ndi awa: Kukana kutentha kwapamwamba: kutha kupirira malo otentha kwambiri, kusunga bata ndi kukhazikika kwa zinthu.
Kukaniza kwabwino: koyenera kugwiritsidwa ntchito m'malo opanikizika kwambiri, kuonetsetsa kuti dongosololi likuyenda bwino.
Kukana kwa Chemical: Imakhala ndi kukana kwazinthu zosiyanasiyana zama mankhwala, kumakulitsa moyo wautumiki wazinthuzo.
Kutalika kwa moyo: Chifukwa cha magwiridwe antchito abwino omwe tatchulawa, zopangidwa ndi PPH zimakhala ndi moyo wautali wautumiki.
Kuphatikiza apo, zinthu za PPH zilinso ndi zabwino zomwe sizikhala ndi poizoni, zosawola, komanso kusakulitsa, zomwe zimapangitsa kuti zikhale zogwira ntchito komanso zotsika mtengo pakuyika mapaipi. Ponseponse, zinthu za PPH zimagwira ntchito yofunika kwambiri m'mafakitale angapo chifukwa chaukadaulo wake wosintha komanso magwiridwe antchito abwino kwambiri, zomwe zimapereka mayankho odalirika pamapulogalamu osiyanasiyana.

Q. Kodi pali kusiyana kotani pakati pa PPH ndi PP?
1. Pali kusiyana kwakukulu pakati pa PPH ndi PP (polypropylene) ponena za zinthu zakuthupi, malo ogwiritsira ntchito, njira zogwirira ntchito, ndi ndalama. Kusiyana kwakukulu pakati pawo ndi motere: 1
Makhalidwe azinthu ndi njira yopangira
PPH (homopolymer polypropylene) imapangidwa posintha kulemera kwakukulu kwa mamolekyu, kutsika kwamadzi osungunuka a homopolymer polypropylene yokhala ndi β, yomwe imakhala ndi kukana kwamphamvu kwamankhwala, kukana kutentha kwambiri, komanso kukana bwino kwa kakwawa, ndipo ndiyoyenera pazovuta kwambiri.
PP (polypropylene) nthawi zambiri imapangidwa ndi polypropylene random copolymer (RPP), yomwe ili ndi kukana kwa dzimbiri ndipo ndiyoyenera kunyamula mankhwala.
2. Munda wofunsira
PPH imagwiritsidwa ntchito nthawi zambiri m'makina amadzi otentha, mafakitale opanga mankhwala, ndi malo omwe amafunikira kutentha kwambiri komanso kukana kwa dzimbiri chifukwa cha kutentha kwambiri komanso kukana kwa mankhwala.
PP imagwiritsidwa ntchito kwambiri ponyamula zakumwa za acidic ndi zamchere m'mafakitale monga mankhwala, electroplating, ndi kusindikiza ndi utoto chifukwa cha kukana kwake kwa dzimbiri.
Processing Technology ndi njira yolumikizira
Mapaipi a PPH nthawi zambiri amalumikizidwa ndi kuwotcherera, kusungunula kotentha, ndi njira zina, zomwe zimakhala ndi mphamvu yolumikizira kwambiri komanso kusindikiza, ndipo ndizoyenera kumadera ovuta monga kuthamanga kwambiri komanso kutentha kwambiri.
Kuphatikiza pa kuwotcherera ndi kulumikizana kotentha kusungunula, mapaipi a PP amathanso kulumikizidwa pogwiritsa ntchito njira zosiyanasiyana monga kusungunuka kwamagetsi, kuwapangitsa kukhala osinthika komanso osavuta.
3. Mtengo
PPH ndiyokwera mtengo kwambiri chifukwa cha kukana kwa dzimbiri komanso kutentha kwambiri, koma imayamikiridwa kwambiri m'mapulojekiti ena omwe amafunikira magwiridwe antchito apamwamba.
PP ili ndi mtengo wotsika kwambiri ndipo ndiyoyenera pulojekiti yomwe imafuna ndalama zambiri.
Mwachidule, pali kusiyana pakati pa PPH ndi PP potengera zinthu zakuthupi, malo ogwiritsira ntchito, njira zogwirira ntchito, ndi ndalama. Kusankhidwa kwa zinthu kumadalira zofunikira zomwe zimagwiritsidwa ntchito ndi chilengedwe.
