Mapaipi aCOMPACT BALL VALVEndi mtundu wa zida zomangira wamba, zomwe zimakondedwa ndi makasitomala ambiri chifukwa cha mawonekedwe awo abwino komanso magwiridwe antchito okwera mtengo.Choncho, lero, tiyamba ndi gulu la mapaipi apulasitiki, ndikudziwitsa aliyense za mapaipi apulasitiki.
Pakadali pano, pali mitundu 6 yotsatirayi yamapaipi apulasitiki omwe amagwiritsidwa ntchito kwambiri pamsika wogulitsa:
1. Chitoliro cha pulasitiki cholimba cha polyvinyl koloyidi, chotchedwa UPVC chitoliro.Ndiwolemera pang'ono, wochepa mphamvu, ali ndi khalidwe lapamwamba lozimitsa moto komanso kukhazikika kwa mankhwala apamwamba, ndipo angagwiritsidwe ntchito ngati ngalande, zimbudzi, mpweya wabwino, ndi zina zotero.
2. Chitoliro cha polyethylene, alias PE chitoliro.Malinga ndi kuchuluka kwa kachulukidwe, zitha kugawidwanso mu chitoliro chachikulu cha polyethylene, chitoliro cha polyethylene chapakati komanso chitoliro chochepa cha polyethylene.Zokwera kwambiri zimakhala ndi mphamvu zambiri komanso kukana kutentha kwapamwamba, ndipo zingagwiritsidwe ntchito pamapaipi a gasi ndi madzi am'tawuni;zapakati-kachulukidwe ali ndi kuuma kwachibadwa ndi mphamvu, koma ali ndi kusinthasintha kwapamwamba komanso kukana kukwawa;otsika kachulukidwe ndi kusinthasintha, elongation Mlingo wautali uli ndi ubwino wina, ndipo kukana kwake, kukhazikika kwa mankhwala ndi ntchito yotsekemera kwambiri ndi yabwino kwambiri, ndipo ingagwiritsidwe ntchito pa ulimi wothirira kumidzi, mphamvu, kulankhulana kwa chingwe, ndi zina zotero.
3. Chitoliro cholumikizidwa ndi polyethylene, chotchedwa PE-X chitoliro.Iwo ali apamwamba kukumbukira, kuteteza chilengedwe, katundu mankhwala, kukana dzimbiri, kukana kutentha, ndipo angagwiritsidwe ntchito popereka kuzirala ndi Kutentha kachitidwe mu nyumba, monga Kutentha mapaipi, chapakati mpweya mapaipi, madzi otentha mapaipi, etc. Itha kugwiritsidwanso ntchito ngati payipi yoyendera chakudya m'makampani azakudya.
4. Chitoliro chosasinthika cha copolymer polypropylene, alias PP-R chitoliro.Ndiwopanda poizoni, wosanunkhiza komanso waukhondo.Ndi kukana kutentha kwapamwamba komanso katundu wa antifreeze, ndi chitoliro chamadzi otentha komanso ozizira.Amagwiritsidwa ntchito kwambiri popangira madzi ozizira ndi otentha akumwa, kupanga zakumwa ndi zoyendera, makina otenthetsera madzi otentha, ndi makina oziziritsira mpweya m'nyumba zaboma ndi mafakitale.
5. chubu cha polybutene, chotchedwa PB chubu.Ili ndi mphamvu zambiri, kukana kwapamwamba kwambiri, ndipo ndiyosavuta kukhazikitsa komanso yosavuta kugwiritsa ntchito.Nthawi yomweyo, mtengo wake ndi wokwera, m'mimba mwake wa chitoliro ndi wocheperako, ndipo umasokonekera mosavuta ndi ma hydrocarbons onunkhira komanso zosungunulira za chlorinated, kotero pali zoletsa zina pantchitoyo.
6. Acrylonitrile-butadiene-styrene pipe, alias ABS chitoliro.Ili ndi kukana kutentha kwakukulu, kukana dzimbiri, kukana kukwawa, ndipo ilibe poizoni, yosanunkhiza, yaukhondo komanso yaudongo, koma ili ndi mawonekedwe osasunthika bwino komanso siyenera malo omwe ali ndi kuwala kwa dzuwa.Kutsidya kwa nyanja, nthawi zambiri amagwiritsidwa ntchito potulutsa zimbudzi, kuthirira, komanso kuyendetsa pansi;ku China, nthawi zambiri amagwiritsidwa ntchito ngati madzi am'nyumba, kunyamula zinthu zowononga, etc.
