Chitoliro cha Madzi Otentha ndi Ozizira cha PB
Chiyambi cha Paipi ya Madzi Otentha ndi Ozizira ya PB
Chitoliro cha Polybutene (PB) ndi polima wochuluka wa molekyulu wosagwira ntchito. Utomoni wa PB ndi chinthu cha polima chopangidwa kuchokera ku butene-1. Uli ndi kachulukidwe kapadera ka 0.937 g/cm3 kristalo, komwe ndi thupi losiyana komanso losinthasintha. Ndi wa zinthu zamakono zopangidwa ndi zinthu zachilengedwe. Ndipo umalimbana ndi kutentha kwambiri, kulimba, kukhazikika kwa mankhwala komanso pulasitiki. Ndi wopanda kukoma, wopanda poizoni, wopanda fungo, uli ndi kutentha kwa -30°C mpaka +100°C, ndipo umalimbana ndi kuzizira, wosagwirizana ndi kutentha, wosagwirizana ndi kupanikizika, wosachita dzimbiri, wosawononga, wosakulitsa, ndipo umakhala ndi moyo wautali (zaka 50-100). Ndipo uli ndi makhalidwe olimbana ndi kukalamba kwa nthawi yayitali. Ndi chimodzi mwa zinthu zamakono kwambiri padziko lonse lapansi. Umagwiritsidwa ntchito kwambiri m'maiko ambiri padziko lonse lapansi. Ndipo uli ndi mbiri ya "golide mu pulasitiki".
Mapaipi a PB (polybutylene) abwino kwambiri okhala ndi madzi ozizira komanso otentha ali ndi zinthu 24. Amagawidwa m'magawo anayi kuyambira dnl6 mpaka dn32. Malinga ndi mndandanda wa mapaipi, amagawidwa m'magulu asanu ndi limodzi: S10, S8, S6.3, S5, S4 ndi 3 .2..
Kugawa kwa Mapaipi a Madzi Otentha ndi Ozizira a PB
Zosungunulira zamoyo zomwe zimapangidwa mumakampani opanga ma semiconductor zimayengedwa ndikubwezeretsedwanso pansi pa njira yofananira kudzera mu chipangizo chowongolera kuti apange zinthu monga stripping liquid B6-1, stripping liquid C01, ndi stripping liquid P01. Zinthuzi zimagwiritsidwa ntchito makamaka popanga ma panel owonetsera ma crystal amadzimadzi, ma semiconductor integrated circuits ndi njira zina.
Makhalidwe a PB Hot ndi Cold Water Pipe
1. Ndi yopepuka, yosinthasintha komanso yosavuta kupanga. Kulemera kwa chitoliro cha PB ndi pafupifupi 1/5 cha chitoliro chachitsulo chopangidwa ndi galvanized. Ndi yosinthasintha komanso yosavuta kunyamula. Utali wocheperako wopindika ndi 6D (D: m'mimba mwake wakunja wa chitoliro). Imagwiritsa ntchito kulumikizana kotentha kapena kulumikizana kwamakina, komwe ndikosavuta kumanga.
2. Ili ndi kulimba bwino, si poizoni komanso yopanda vuto. Chifukwa cha kulemera kwake kwakukulu kwa mamolekyu, kapangidwe kake ka mamolekyu ndi kokhazikika. Si poizoni komanso yopanda vuto ndipo imatha kugwira ntchito kwa zaka zosachepera 50 popanda kuwala kwa ultraviolet.
3.t imakhala ndi kukana chisanu bwino komanso kutentha. Ngakhale pa -20°C, imatha kukhalabe ndi kukana kutentha kochepa. Pambuyo posungunuka, chitolirocho chimabwerera ku mawonekedwe ake oyambirira. Pansi pa kutentha kwa 100℃, mbali zonse za magwiridwe antchito zimasungidwa bwino.
4. Ili ndi makoma osalala a mapaipi ndipo siimakula. Poyerekeza ndi mapaipi opangidwa ndi galvanized, imatha kuwonjezera kuyenda kwa madzi ndi 30%.
5. N'zosavuta kukonza. Chitoliro cha PB chikakwiriridwa, sichimalumikizidwa ku konkire. Chikawonongeka, chingakonzedwe mwachangu mwa kusintha chitolirocho. Komabe, ndi bwino kugwiritsa ntchito njira yophimba (chitoliro mu chitoliro) pokwirira mapaipi apulasitiki. Choyamba, phimbani chitoliro cha PB ndi chitoliro cha PVC chokhala ndi khoma limodzi, kenako chikwirireni, kuti kukonza kukhale kotsimikizika mtsogolo.
