PVC Solvent Cement: Tetrahydrofuran, Cyclohexanone and PVC Resin (Gheen, US 3,539,166)
PVC pipe is not glued; it is welded by a solvent that softens both faces, which then dry as one. Gheen's cement is fast tetrahydrofuran, slow cyclohexanone and a little PVC resin for body.
Result: a solvent cement that bonds PVC pipe ends into their fittings.

Le blueprint yenza
Ama-blueprint ahlobene
Lama-blueprint abelana ngolwazi — amasu, izinto noma izimiso
CC0 Isizinda Somphakathi
Le blueprint ikhishwe ngaphansi kwe-CC0. Ukhululekile ukukopisha, ukuguqula, ukusabalalisa, nokusebenzisa ngaphandle kwemvume.
Sekela uMenzi ngokuthenga imikhiqizo nge-Blueprint yabo IKhomishane Yomenzi kumiswe ngabathengisi, noma dala inguqulo entsha yale Blueprint bese uyifaka njengoxhumaniso ku-Blueprint yakho ukuze wabelane ngemali engenayo.
