Chitoliro chotentha choviikidwa ndi mabati

Chitsulo chosungunuka chimagwirizana ndi matrix yachitsulo kuti chipange gawo la alloy, kotero kuti matrix ndi chophimbacho ziphatikizidwe. Kuyika galvanizing yotentha ndikuyamba kuyika payipi yachitsulo, kuti muchotse chitsulo chosakanizika pamwamba pa payipi yachitsulo, mutatha kuyika, kudzera mu ammonium chloride kapena zinc chloride aqueous solution kapena ammonium chloride ndi zinc chloride mixed aqueous solution tank kuti ziyeretsedwe, kenako mu thanki yoyika pulasitiki yotentha. Kuyika galvanizing yotentha kumakhala ndi ubwino woyika pulasitiki yofanana, kumamatira mwamphamvu komanso kukhala ndi moyo wautali. Njira zambiri kumpoto zimagwiritsa ntchito njira yobwezeretsanso zinc ya galvanizing direct coil pipe.

Chitoliro chozizira chopangidwa ndi galvanizing

Magalasi ozizira ndi amagetsi, kuchuluka kwa magalasi ndi kochepa kwambiri, 10-50g/m2 yokha, kukana kwake dzimbiri ndi kosiyana kwambiri ndi mapaipi otentha amagetsi. Opanga mapaipi okhazikika amagetsi, pofuna kutsimikizira kuti ndi abwino, ambiri sagwiritsa ntchito magalasi amagetsi (mapulati ozizira). Mabizinesi ang'onoang'ono okha omwe ali ndi zida zakale ndi omwe amagwiritsa ntchito magalasi amagetsi, ndithudi, mitengo yawo ndi yotsika mtengo. M'tsogolomu, mapaipi ozizira amagetsi saloledwa kugwiritsidwa ntchito ngati mapaipi amadzi ndi gasi.

Chitoliro chachitsulo chotenthedwa ndi madzi otentha

Zochitika zovuta komanso za mankhwala zimachitika pakati pa chubu chachitsulo ndi bafa losungunuka kuti apange gawo lolimba la zinc-iron alloy lokhala ndi kukana dzimbiri. Gawo la alloy limaphatikizidwa ndi gawo loyera la zinc ndi matrix ya chitoliro chachitsulo. Chifukwa chake, kukana kwake dzimbiri kumakhala kolimba.

Pambuyo pa chitukuko cha chitoliro chachitsulo chotentha chopangidwa ndi galvanized m'zaka za m'ma 1960 mpaka 1970, khalidwe la malonda lakhala likukwera kwambiri, 1981 mpaka 1989 idapatsidwa mphoto ya Unduna wa Zamalonda Zapamwamba ndi Siliva wa Dziko Lonse, kupanga kunakulanso kwa zaka zambiri, 1993 kutulutsa matani opitilira 400,000, 1999 kutulutsa matani opitilira 600,000, ndikutumizidwa ku Southeast Asia, Africa, United States, Japan, Germany Mayiko ndi madera. Mapaipi opangidwa ndi galvanized otentha amagwiritsidwa ntchito kwambiri ngati mapaipi amadzi ndi mapaipi a gasi, ndipo kufotokozera kofala ndi +12.5 ~ + 102 mm. Pambuyo pa zaka za m'ma 1990, chifukwa cha chidwi cha boma pa kuteteza chilengedwe, kuwongolera mabizinesi owononga kwambiri kukukulirakulira, "zinyalala zitatu" zomwe zimapangidwa popanga mapaipi otenthetsera ndi madzi otentha zimakhala zovuta kuthetsa, kuphatikiza ndi chitukuko chachangu cha mapaipi otenthetsera ndi zitsulo zosapanga dzimbiri, mapaipi a PVC ndi mapaipi ophatikizika, komanso boma kuti lilimbikitse kugwiritsa ntchito zida zomangira mankhwala, kugwiritsa ntchito mapaipi otenthetsera ndi zitsulo zotenthetsera ndikoletsedwa, zomwe zimapangitsa kuti pakhale mapaipi otenthetsera ndi madzi otentha kwambiri. Beam ndi malire, chitoliro chotenthetsera ndi madzi otentha pambuyo pake chinakula pang'onopang'ono.

Chitoliro chachitsulo chozizira chopangidwa ndi galvanic

Zinc wosanjikiza ndi wamagetsi, ndipo zinc wosanjikiza umayikidwa pawokha ndi chitsulo cha payipi. Zinc wosanjikiza ndi woonda, ndipo zinc wosanjikiza umangolumikizidwa ku chitsulo cha payipi ndipo umagwa mosavuta. Chifukwa chake, kukana kwake dzimbiri ndi kochepa. M'nyumba zatsopano zokhala anthu, n'koletsedwa kugwiritsa ntchito mapaipi ozizira achitsulo ngati mapaipi operekera madzi.
