Chifukwa chiyani tiyenera kusankha valavu ya PPH, kuyika chitoliro kapena chitoliro

Valavu ya PPH ndi mtundu wa valve yopangidwa ndi polypropylene (PP), yomwe ili ndi makhalidwe opepuka, kukonza kosavuta, kusinthasintha kwabwino ndi zina zotero, kotero pali ntchito zambiri pakupanga ndi moyo. Zotsatirazi ndi zina zomwe zimagwiritsidwa ntchito nthawi zambiri:

Makampani a Chemical:

M'makampani opanga mankhwala, ma valve a PPH amagwiritsidwa ntchito kwambiri pakuwongolera mapaipi azinthu zosiyanasiyana zowononga, monga asidi, alkali, mchere ndi zina zotero. Chifukwa cha kukana kwambiri kwa dzimbiri komanso mphamvu zolimbana ndi ukalamba, ma valve a PPH amatha kugwira ntchito mokhazikika kwa nthawi yayitali, zomwe zimatsimikizira chitetezo ndi kukhazikika kwa kupanga mankhwala.

Makampani oyeretsa madzi:

Mavavu a PPH amagwiritsidwanso ntchito kwambiri poyeretsa madzi komanso kuyeretsa zimbudzi. Chifukwa cha ntchito yake yabwino yaukhondo, ilibe zinthu zapoizoni, ma valve a PPH mu njira yothetsera madzi sangabweretse kuipitsidwa kwachiwiri kwa madzi, kotero mu makampani opangira madzi amakondedwa kwambiri.

Makampani azakudya:

M'makampani azakudya, mavavu a PPH amagwiritsidwa ntchito kwambiri pokonza ndi kuyika chakudya chifukwa cha mawonekedwe awo omwe alibe poizoni, osanunkhiza komanso osachita dzimbiri. Mwachitsanzo, popanga zakumwa, ma valve a PPH angagwiritsidwe ntchito poyang'anira kayendedwe ndi kayendedwe ka zakumwa; pakuyika chakudya, mavavu a PPH atha kugwiritsidwa ntchito kuwongolera ma vacuum system ndi ma pneumatic system.

Makampani opanga mankhwala:

M'makampani opanga mankhwala, ma valve a PPH amagwiritsidwa ntchito kwambiri popanga, kusunga ndi kunyamula mankhwala chifukwa cha ukhondo wawo komanso kukana bwino kwa dzimbiri. Mwachitsanzo, ma valve a PPH angagwiritsidwe ntchito kuwongolera kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake posungira mankhwala, ma valve a PPH angagwiritsidwe ntchito poyang'anira chinyezi ndi kutentha kwa nyumba yosungiramo katundu.

Pa msika, pali UPVC, CPVC, PPH, PVDF, FRPP vavu, ndi dongosolo chitoliro. Chifukwa chotsatira: Chifukwa chiyani tiyenera kusankha valavu ya PPH, kuyika chitoliro kapena chitoliro?

Kodi Makhalidwe a PPH ndi chiyani?

Polypropylene Homopolymer (PP-H) ndi mtundu wina wa PP. Ili ndi kutentha kwabwinoko & kukana kukwawa kuposa PPR, komanso kutsika kwamphamvu kwa kutentha.

Pakalipano mapaipi & zopangira za PPH ndizodalirika kwambiri m'mafakitale opangira madzi ndi madzi, chifukwa cha mawonekedwe awo amankhwala komanso kuwotcherera, zomwe zimatsimikizira kuti mapaipi azikhala ndi makina osindikizira abwino kwambiri. Kuvomerezedwa ndi Health Organisation yokhala ndi mawonekedwe monga Eco-wochezeka komanso kukana kutentha kwambiri, mapaipi a PPH/PPR & zokometsera zatengedwa ngati njira yabwino kwambiri yothetsera mapaipi.

Kutentha kwakukulu kwa mapaipi a PPH ndi 110 ℃, ndipo nthawi zambiri amagwiritsidwa ntchito pansi pa 90 ℃. Amagwiritsidwa ntchito potumiza madzi ozizira, kusamutsa zinthu zowononga, ma ducts a fume, makina a electrolyze, ndi mapaipi ena okhala ndi zakumwa za asidi.

Kodi PPH Physical Properties ndi chiyani?

Kodi njira yolumikizira zinthu za PPH ndi chiyani?

Dongosolo la chitoliro la PPH limalumikizidwa ndi kusungunuka kotentha, komwe kumatha kugawidwa kukhala kuwotcherera kwa socket yotentha komanso kuwotcherera kwa matako. Njira zenizeni zowotcherera socket socket ndi motere:

Atsogolereni mapaipi mu chotenthetsera molunjika mpaka kukuya komwe kwalembedwa. Pakadali pano, kanikizani choyikacho pa chotenthetsera ndikufikira kuya komwe kwalembedwa.

Atsogolereni mapaipi mu chotenthetsera molunjika mpaka kukuya komwe kwalembedwa. Pakadali pano, kanikizani choyikacho pa chotenthetsera ndikufikira kuya komwe kwalembedwa.

Nthawi yowotcha iyenera kutsatiridwa ndi zomwe zili pansi pa tebulo (tsamba lotsatira). Pambuyo Kutentha nthawi, chotsani chitoliro ndi zoyenerera kuchokera ku chotenthetsera nthawi yomweyo ndikuwasonkhanitsira kukuya komwe kwalembedwa molunjika kuti pakhale chophulika ndi malo osonkhanitsira. Munthawi yogwira ntchito, kusintha kwakung'ono kungapangidwe koma kuzungulira kuyenera kuletsedwa. Kuteteza chitoliro ndi kukwanira kuti zisaphwanyidwe, kupindika, ndi kutambasula.

Ngati kutentha kwa chilengedwe kuli kochepa kuposa 5 ℃, onjezerani nthawi yotentha ndi 50%

Mukalumikiza, ikani mbali zowotcherera pachitsulo chotentha mpaka mbali yonseyo ikhudze chitsulo chotentha, mbali ndi mbali, ndipo imatha kuwona mawonekedwe ake. Pamene flanging kutalika mozungulira lonse circumference chubu kapena lonse pamwamba pa mbale kufika mtengo chofunika, ndiye limagwirizana.

Pambuyo pa kuwotcherera kwa matako otentha, cholumikiziracho chidzakhazikika mu makina owotcherera otentha asungunula, ndikuziziritsa cholumikizira molingana ndi nthawi yozizirira zomwe zafotokozedwa m'malamulo osungira komanso kuziziritsa kwa makina owotcherera otentha. Mukaziziritsa, chepetsani kukanikiza mpaka ziro, ndiyeno chotsani chitoliro/zowonjezera zowotcherera.
