Kutheni kufuneka sikhethe ivalve ye-PPH, ukufaka umbhobho okanye umbhobho

I-valve ye-PPH luhlobo lwevalve eyenziwe nge-polypropylene (PP) impahla, eneempawu zokulula, ukugcinwa okulula, ukutshintshiselana okulungileyo kunye nokunye, ngoko kukho ezininzi ukusetyenziswa kwimveliso kunye nobomi. Oku kulandelayo lusetyenziso oluqhelekileyo:

Ishishini lemichiza:

Kwishishini lemichiza, iivalve ze-PPH zisetyenziswa ngokubanzi kulawulo lwemibhobho yemithombo eyahlukeneyo eyonakalisayo, njenge-asidi, i-alkali, ityuwa njalo njalo. Ngenxa yokumelana nokugqwesa okugqwesileyo kunye neempawu ezinamandla zokulwa nokuguga, iivalve ze-PPH zinokusebenza ngokuzinzileyo ixesha elide, eliqinisekisa ngokufanelekileyo ukhuseleko kunye nokuzinza kwemveliso yeekhemikhali.

Ishishini lokucocwa kwamanzi:

Iivalve ze-PPH zikwasetyenziswa ngokubanzi kwintsimi yokucocwa kwamanzi kunye nokucocwa kwamanzi amdaka. Ngenxa yokusebenza kwayo okugqwesileyo kococeko, ayiqukethe izinto ezinobuthi, iivalvu ze-PPH kwinkqubo yokucoca amanzi aziyi kuvelisa ukungcoliseka kwesibini komgangatho wamanzi, ngoko ke kushishino lokucoca amanzi kuthandwa kakhulu.

Ishishini lokutya:

Kwishishini lokutya, iivalvu ze-PPH zisetyenziswa ngokubanzi ekusetyenzweni kokutya kunye neenkqubo zokupakisha ngenxa yeempawu zazo ezingenatyhefu, ezingenavumba kunye ne-corrosion-resistant. Ngokomzekelo, kwimveliso yesiselo, iivalve ze-PPH zingasetyenziselwa ukulawula ukuhamba kunye nolwalathiso lokuhamba kweziselo; ekupakishweni kokutya, iivalve ze-PPH zingasetyenziselwa ukulawula iinkqubo ze-vacuum kunye neenkqubo ze-pneumatic.

Umzi mveliso wamachiza:

Kumashishini amayeza, iivalve ze-PPH zisetyenziswa ngokubanzi kwimveliso, ukugcinwa kunye nokuthutha amayeza ngenxa yokucoceka kwabo okuphezulu kunye nokuchasana kokubola. Ngokomzekelo, iivalve ze-PPH zingasetyenziselwa ukulawula indlela yokuhamba kunye nesantya sokuhamba kweyeza ngexesha lokuzaliswa; kwindawo yokugcina iyeza, iivalvu ze-PPH zingasetyenziselwa ukulawula ukufuma kunye nobushushu bendawo yokugcina impahla.

Kwimarike, kukho i-UPVC, iCPVC, iPPH, iPVDF, ivalve yeFRPP, kunye nenkqubo yombhobho. Isizathu esilandelayo sokuba Kutheni kufuneka sikhethe ivalve ye-PPH, ukufaka umbhobho okanye umbhobho?

Loluphi uphawu lweMathiriyeli ye-PPH?

I-Polypropylene Homopolymer (PP-H) yolunye uhlobo lwePP. Inobushushu obungcono kunye nokuchasana nokunyuka kunePPR, kwaye inamandla asezantsi obushushu obunefuthe.

Ngoku imibhobho ye-PPH kunye nokufakelwa kweyona nto inokuthenjwa kwimibhobho yamanzi kunye nezityalo zokubonelela ngamanzi, ngenxa yeempawu zabo zekhemikhali kunye ne-fusion welding, eqinisekisa ukuba imibhobho ibe nenkqubo eqinileyo yokutywina. Ivunywe nguMbutho wezeMpilo kunye neempawu ezifana ne-Eco-friendly kunye nokumelana nokushisa okuphezulu, iipayipi ze-PPH / PPR kunye nezixhobo zithathwe njengenye yesisombululo esihle kwiinkqubo zombhobho.

Ubushushu obuphezulu bemibhobho ye-PPH yi-110℃, kwaye iqhele ukusetyenziswa ngaphantsi kwe-90℃. Zisetyenziselwa ukugqithiselwa kwamanzi okupholisa, ukuhanjiswa kwemathiriyeli eyonakalisayo, imibhobho yomsi, iinkqubo ze-electrolyze, kunye nezinye iinkqubo zemibhobho ezinolwelo lweasidi.

Yintoni iiPropati zePPH zePhysical Properties?

Yintoni indlela yokudibanisa iimveliso ze-PPH?

Inkqubo yombhobho we-PPH idityaniswe yi-hot melt, enokuthi yohlulwe ibe yi-hot melt socket welding kunye ne-hot melt butt welding. Amanyathelo athile e-hot melt socket welding alandelayo:

Khokhela imibhobho kwisifudumezi ngqo kubunzulu bendibano ephawulweyo. Okwangoku, tyhala ukufakela kwi-heater kwaye ufikelele kubunzulu obuphawulweyo.

Khokhela imibhobho kwisifudumezi ngqo kubunzulu bendibano ephawulweyo. Okwangoku, tyhala ukufakela kwi-heater kwaye ufikelele kubunzulu obuphawulweyo.

Ixesha lokufudumeza kufuneka lihambelane namaxabiso akwitheyibhile engaphantsi (iphepha elilandelayo). Emva kwexesha lokufudumeza, susa umbhobho kunye nokufakwa kwisifudumezi ngokukhawuleza kwaye uzihlanganisele kubunzulu obuphawulweyo ngokuthe tye ukuze kubekho i-bulge yendawo yokuhlanganisa. Ngexesha lokusebenza, ulungelelwaniso oluncinci lunokwenziwa kodwa ukujikeleza kufuneka kuthintelwe. Ukugcina umbhobho kunye nokufakela ukuba ungakrolwa, ugobe kwaye wolulwe.

Ukuba ubushushu bendawo bungaphantsi kwe-5℃, yandisa ixesha lokufudumeza nge-50%

Xa ulungelelanisa, beka amacala e-welding kwintsimbi eshushu de icala lonke lizalise intsimbi eshushu ngokupheleleyo, icala ukuya kwelinye, kwaye inokuqwalasela ukubunjwa kwe-flanging. Xa ukuphakama kwe-flanging kujikeleze yonke i-circumference yetyhubhu okanye yonke into ephezulu yepleyiti ifikelela kwixabiso elifunekayo, ngoko ihambelana.

Emva kwe-welding eshushu yokunyibilika kwe-butt, isinxibelelanisi siya kulungiswa kumatshini wokuwelda we-butt we-melt, kunye nokupholisa isinxibelelanisi ngokwexesha lokupholisa elichazwe kwimimiselo yogcino loxinzelelo kunye nokupholisa umatshini we-welding we-butt oshushu onyibilikayo. Emva kokupholisa, nciphisa uxinzelelo kwi-zero, uze ususe umbhobho odibeneyo / izixhobo.

Itheyibhile yesalathiso yenkqubo yokunyibilika kwe-butt eshushu yeemibhobho ze-PPH kunye nezifakelo
