Kungani kufanele sikhethe i-valve ye-PPH, ukufaka ipayipi noma ipayipi

I-valve ye-PPH iwuhlobo lwe-valve eyenziwe nge-polypropylene (PP) impahla, enezici zokungasindi, ukugcinwa okulula, ukushintshashintsha okuhle nokunye, ngakho-ke kukhona ukusetshenziswa okuningi ekukhiqizeni nasekuphileni. Okulandelayo okunye ukusetshenziswa okuvamile:

Imboni yamakhemikhali:

Embonini yamakhemikhali, ama-valve e-PPH asetshenziswa kakhulu ekulawuleni amapayipi emidiya ehlukahlukene egqwalayo, njenge-asidi, i-alkali, usawoti nokunye. Ngenxa yokumelana nokugqwala okuhle kakhulu kanye nezakhiwo eziqinile zokulwa nokuguga, ama-valve e-PPH angasebenza ngokuzinza isikhathi eside, okuqinisekisa ngempumelelo ukuphepha nokuzinza kokukhiqizwa kwamakhemikhali.

Imboni yokuhlanza amanzi:

Ama-valve e-PPH nawo asetshenziswa kabanzi emkhakheni wokuhlanza amanzi nokuhlanza indle. Ngenxa yokusebenza kwayo okuhle kakhulu kwenhlanzeko, ayinazo izinto ezinobuthi, ama-valve e-PPH enqubweni yokwelashwa kwamanzi ngeke akhiqize ukungcoliswa kwesibili kwekhwalithi yamanzi, ngakho-ke embonini yokuhlanza amanzi ithandwa kakhulu.

Imboni yokudla:

Embonini yokudla, ama-valve e-PPH asetshenziswa kakhulu ekucubunguleni ukudla nasezinqubweni zokupakisha ngenxa yezimpawu zawo ezingenabuthi, ezingenaphunga kanye nezimelana nokugqwala. Isibonelo, ekukhiqizeni isiphuzo, ama-valve e-PPH angasetshenziswa ukulawula ukugeleza nokuqondiswa kokugeleza kweziphuzo; ekufakweni kokudla, ama-valve e-PPH angasetshenziswa ukulawula izinhlelo ze-vacuum kanye nezinhlelo ze-pneumatic.

Imboni yezemithi:

Embonini yezemithi, ama-valve e-PPH asetshenziswa kakhulu ekukhiqizeni, ekugcinweni nasekuthuthweni kwemithi ngenxa yokuhlanzeka kwawo okuphezulu kanye nokumelana nokugqwala okuhle. Isibonelo, ama-valve e-PPH angasetshenziswa ukulawula isiqondiso sokugeleza kanye nesilinganiso sokugeleza kwemithi ngesikhathi sokugcwalisa; endaweni yokugcina imithi, ama-valve e-PPH angasetshenziswa ukulawula umswakama kanye nezinga lokushisa kwendawo yokugcina impahla.

Emakethe, kukhona i-UPVC, CPVC, PPH, PVDF, FRPP valve, kanye nesistimu yamapayipi. Isizathu esilandelayo sokuthi Kungani kufanele sikhethe i-valve ye-PPH, ukufaka ipayipi noma ipayipi?

Iyini Isici sempahla ye-PPH?

I-Polypropylene Homopolymer (PP-H) ingenye uhlobo lwe-PP. Inezinga lokushisa elingcono kanye nokumelana nokukhuphuka kune-PPR, futhi inamandla okushisa aphansi.

Njengamanje amapayipi nokufakwa kwe-PPH athembeke kakhulu ezimbonini zamapayipi namapayipi eziphakela amanzi, ngenxa yezici zawo zamakhemikhali kanye nokushisela okuhlanganisiwe, okuqinisekisa ukuthi amapayipi amapayipi abe nohlelo oluqinile oluqinile. Kugunyazwe Inhlangano Yezempilo enezici ezifana ne-Eco-friendly kanye nokumelana nezinga lokushisa eliphezulu, amapayipi e-PPH/PPR nokufakwa kuthathwe njengesinye sesixazululo esingcono kakhulu sezinhlelo zamapayipi.

Izinga lokushisa eliphezulu lamapayipi e-PPH ngu-110 ℃, futhi ngokuvamile asetshenziswa ngaphansi kuka-90 ℃. Zisetshenziselwa ukudluliswa kwamanzi okupholisa, ukudluliswa kwezinto ezibolayo, imigudu yomusi, amasistimu e-electrolyze, nezinye izinhlelo zamapayipi anoketshezi oluyi-asidi.

Iyini i-PPH Physical Properties?

Ithini indlela yokuxhuma imikhiqizo ye-PPH?

Isistimu yamapayipi e-PPH iboshelwe ukuncibilika okushisayo, okungahlukaniswa kube ukushisela kwesokhethi encibilikayo okushisayo kanye nokushisela kwe-hot melt butt. Izinyathelo ezithile zokushisela i-hot melt socket zimi kanje:

Qondisa amapayipi ku-heater ngqo ekujuleni komhlangano omakiwe. Okwamanje, cindezela okokufaka ku-heater futhi ufinyelele ekujuleni okumakiwe.

Qondisa amapayipi ku-heater ngqo ekujuleni komhlangano omakiwe. Okwamanje, cindezela okokufaka ku-heater futhi ufinyelele ekujuleni okumakiwe.

Isikhathi sokushisisa kufanele sihambisane namanani akuthebula elingaphansi (ikhasi elilandelayo). Ngemuva kwesikhathi sokushisa, susa ipayipi kanye nokufaka ku-heater ngokushesha futhi ukuhlanganise ekujuleni okuphawuliwe okuqondile ukuze kube nendawo yokuhlangana. Phakathi nesikhathi sokusebenza, ukulungiswa okuncane kungenziwa kodwa ukuzungezisa kumele kwenqatshelwe. Ukugcina ipayipi nokulingana ukuze lingaklinwa, ligotshwe, futhi lelulwe.

Uma izinga lokushisa lemvelo lingaphansi kuka-5 ℃, nwebisa isikhathi sokushisisa ngo-50%

Uma uqondana, faka izinhlangothi zokushisela ensimbi eshisayo kuze kube yilapho lonke uhlangothi lugcwele luthinta insimbi eshisayo ngokuphelele, eceleni, futhi ikwazi ukubona ukwakheka kwe-flanging. Lapho ukuphakama okuphenduphendukayo okuzungeze yonke indilinga yeshubhu noma yonke indawo ephezulu yepuleti kufinyelela inani elidingekayo, khona-ke kuyaqondiswa.

Ngemuva kokushisela okushisayo kwe-butt, isixhumi kufanele simiswe emshinini wokushisela we-hot melt butt, futhi sipholise isixhumi ngokuvumelana nesikhathi sokupholisa esishiwo emithethweni yokugcinwa kwengcindezi nokupholisa umshini wokushisela we-hot melt butt. Ngemva kokupholisa, yehlisa ingcindezi ibe ziro, bese ukhipha ipayipi/izifakelo ezishiselwe.
