Yintoni iValve yeBhola yeWeld yeSolvent
A ivalvu yebhola ye-weld yesinyibilikisiisebenzisa i-chemical fusion bonding endaweni ye-thermal welding ukuze idibanise ngokusisigxina izinto zevalvu kwiinkqubo zepayipi. Ngokungafaniyo neevalvu zemveli ezidityanisiweyo, i-solvent welding inyibilikisa iileya zomphezulu wezinto zePVC/CPVC, idale amajoyinti angavuziyo ngokusebenzisa i-molecular bonding.
Iimpawu eziPhambili zoLwakhiwo
– Ulwakhiwo olungenako ukuvuza: Ukuhlanganiswa kweekhemikhali kudala unxibelelwano lwe-monolithic
– Ukumelana nokugqwala: Ilungele ukusetyenziswa kwezixhobo ezirhabaxa (iiasidi, izinyibilikisi)
– Uyilo olungenalo ulondolozo: Amalungu asisigxina asusa ukuwohloka kwetywina
– Ufakelo oluncinci: 40% ilula kunezinye iindlela ezijikelezileyo
– Ukuhamba komoya ogcweleyo: Uxinzelelo oluncinci oluthotywayo kwimibhobho
Izicelo eziphambili
1. Ukucubungula iikhemikhali: i-HCl, i-H₂O₂, kunye nemigca yokudlulisa i-solvent
2. Unyango lwaManzi: Iinkqubo zeChlorination kunye neeyunithi zokucoca
3. Amayeza: Ukuphathwa kolwelo okuhambelana ne-USP Class VI
4. Ukwenziwa kweeSemiconductor: Ukusasazwa kwamanzi acocekileyo kakhulu
Ukuwelda kweSolvent vs. Ukuwelda kweNdalo
| I-Factor | Ukuwelda kweSolvent | Ukuwelda okushushu |
| Indlela yoQhagamshelo | Ukuhlanganiswa kweekhemikhali | Ukunyibilika kwesinyithi |
| Ukuhambelana kwezinto | I-PVC/CPVC kuphela | Iintsimbi kunye nee-alloys |
| Ukumelana nobushushu | 60°C (140°F) ubuninzi | 400°C+ (750°F+) |
| Isakhono sokufaka | Uqeqesho oluphantsi luyafuneka | Kufuneka umthungi oqinisekisiweyo |
NSW: Umvelisi weValve yeBhola yeWeld eThembekileyo
NjengeIsiqinisekiso se-API 6Dumenzi wevalvu yebhola edityanisiweyo, i-NSW inika:
–Uluhlu olupheleleyo lobungakananiIivalvu zebhola ze-weld ze-solvent eziyi-½” ukuya kwi-60″
–Uvavanyo loxinzelelo: Iklasi ye-150 ukuya kwiKlasi ye-900
–Iinketho zezinto eziphathekayoUlwakhiwo lwe-PVC, CPVC, PP, kunye ne-PVDF
–Uyilo olukhethekileyo:
– Iindlela ezi-3 zokujika
– Iindidi ezikhuselekileyo emlilweni (API 607)
– Iimodeli zeCryogenic (-196°C)
– Ii-actuators ze-ISO 5211 ezichasene nokungaguquki
*Ingqiqo yoShishino*: Iivalvu ze-solvent weld zilawula i-78% yeenkqubo zemibhobho ye-PVC yamachiza eMntla Melika ngenxa yokuba azikhuphi umbane kwaye zisebenza iminyaka engama-25 (ezihambelana ne-ASME B31.3).
