Dixon Industrial Tape ndeye isingadhure pombi shinda sealant inofanirwa kuwana nzvimbo mubhokisi rematurusi ese.Zviri nyore kushandisa, hapana njodzi yekudonha panzvimbo dzakatetepa, uye haidi kucheneswa.Iyi chena PTFE tepi inoshanda pakuvhara marudzi ese emapombi esimbi anotakura mvura kana mweya.Inogona zvakare kushandiswa kusimbisa tambo dzekare kana screw yakasununguka.
Iyi tepi yeDixon ine tembiricha yekushanda ye -212 degrees Fahrenheit kusvika 500 degrees Fahrenheit.Kunyange iyo yakakodzera kune akawanda epamba uye ekutengesa maapplication, haina kugadzirirwa kudzvanywa kana gasi kushandiswa.Ichi chigadzirwa chakafara ¾” uye chinokodzera shinda zhinji dzepombi.Kureba kwayo kunosvika 43 tsoka dzekuwedzera mari.
Oatey 31230 Tube Fitting Compound yakanakisa chinangwa chepombi shinda sealant.Ichi chigadzirwa chinonyanya kushandiswa kune mapaipi emvura;Ichi chigadzirwa chinoenderana neNSF-61, iyo inoisa mwero wezvigadzirwa zvemvura zvemanisipala.Nekudaro, inogona zvakare kuvhara kuvuza mumitsara inotakura chiutsi, mweya, zvinwiwa zvinoparadza uye akawanda maasidhi.Oatey fitting compounds akakodzera simbi, simbi, mhangura, PVC, ABS, Cycolac uye polypropylene.
Iyi fomula yakapfava inomira tembiricha kubva paminus 50 degrees kusvika 500 degrees Fahrenheit uye air pressure inosvika 3,000 psi uye mvura pressure inosvika 10,000 psi.Iyo eco-inoshamwaridzika uye isiri-chepfu formula inobvumira kuti ishandiswe sepombi yekuputira (kunyangwe ichigona kukonzera kushatirwa kweganda).
Dambudziko guru rekushandisa zvisimbiso pashinda dzePVC nderekuti vashandisi vanowanzofanira kuomesa majoini, izvo zvinogona kutungamirira mukutsemuka kana kubvisa.PTFE matepi haakurudzirwe sezvaanozora shinda uye kuita kuti zvive nyore kuomesa zvakare.Rectorseal T Plus 2 ine PTFE pamwe nepolymer fibers.Vanopa kuwedzera kukweshera uye chisimbiso chakachengeteka pasina simba rakawandisa.
Iyi emollient yakakodzerawo kune zvimwe zvakawanda zvepombi zvinhu, zvinosanganisira simbi nemapurasitiki.Inogona kuvhara pombi dzinotakura mvura, gasi nemafuta pa -40 kusvika 300 madhigirii Fahrenheit.Kudzvinyirira kwegasi kunogumira ku2,000 psi uye kudzvinyirira kwemvura kunogumira ku10,000 psi.Inogonawo kuva pasi pekumanikidzwa pakarepo mushure mekushandisa.
Kazhinji, tepi chena yePTFE inoshandiswa kune zvakajairika uye yero PTFE tepi (semuenzaniso Harvey 017065 PTFE Sealant) inoshandiswa kugadzira magasi.Iyi inorema basa tepi inosangana neUL gasi kuchengetedza zvinodiwa.Iyi tepi yeHarvey chigadzirwa chakasiyana-siyana chinokurudzirwa kwete chete gasi rechisikigo, butane uye propane, asiwo nemvura, mafuta uye peturu.
Iyi tepi yero inovhara ese simbi uye akawanda epurasitiki pombi, zvisinei, sematepi ese ePTFE, haikurudzirwe kushandiswa paPVC.Ukobvu hwayo hwakakodzerawo mabasa akadai sekugadzirisa tambo pamabhoti kana mavharuvhu fittings.Iyo tepi ine tembiricha yekushanda ye minus 450 madhigirii kusvika pa500 madhigirii Fahrenheit uye yakatemerwa kumanikidzwa kusvika ku100 psi.
Air duct pendi ndeyese-chinangwa musanganiswa, asi kazhinji inouya mune inokwana 4 ounce makani.Izvi zvakawandisa kumaturusi mazhinji.Rectorseal 25790 inouya muchubhu iri nyore kuwana nyore.
Inokodzera kupinza epurasitiki nesimbi pombi, iyi yakapfava yekurapa musanganiswa yakakodzera kuvhara pombi dzine akasiyana magasi uye zvinwiwa, kusanganisira mvura yekunwa.Kana ikashandiswa negasi, mhepo, kana mvura inodzvinyirirwa kusvika ku100 psi (inokodzera kuisirwa mudzimba zhinji), inogona kudzvanywa pakarepo mushure mebasa.Chigadzirwa chacho chine tembiricha ye -50 ° F kusvika 400 ° F uye yakanyanya kumanikidzwa ye12,000 psi yezvinwiwa uye 2,600 psi yemagasi.
Kune akawanda pombi shinda yekuisa chisimbiso mapurojekiti, vashandisi havagone kukanganisa neGasoila - SS16, yakanyanya tembiricha inodzivirira isingaomese PTFE paste.Vatengi vanosarudza kudzivirira kukanganisa kwekunamira vanogona kufunga Dixon Seal Tape, inokwanisika asi inoshanda-yese-chinangwa PTFE tepi.
Kupeta kusarudzwa kwedu kweakanakisa pombi shinda sealants, takatarisa maviri emhando dzechigadzirwa chakakurumbira: tepi uye chisimbiso.Rondedzero yedu yakakurudzirwa inopa vatengi sarudzo dzezvakasiyana-siyana zvekushandisa, kubva kuPVC kuenda kumapombi esimbi emvura kana gasi, isu tine mhinduro inonyatso kuenderana nemamiriro ako ezvinhu.
Munguva yekutsvagisa kwedu, takava nechokwadi chekuti zvese zvatinokurudzira zvaibva kumhando dzinozivikanwa dzinoshandiswa nenyanzvi dzine ruzivo.Yese yedu yakanaka lockpicks inomira tembiricha yakakwira uye inopa chisimbiso chakachengeteka.
Panguva ino, iwe wakadzidza nezve akasiyana tekinoroji maitiro ekufunga kana uchisarudza pombi tambo sealant.The Best Sarudzo chikamu chinonyora mamwe akanakisa pombi tambo sealants kune chaiwo maapplication, asi kana uchine mibvunzo isina kupindurwa, tarisa ruzivo runobatsira pazasi.
Mapombi epombi anowanzo nyatso kuenderana nePVC uye Rectorseal 23631 T Plus 2 pombi shinda sealant ndiyo yakanakisa komisheni yechinangwa ichi.
Mazhinji sealants akagadzirirwa kushandiswa zvachose, asi mazhinji anogona kubviswa kana zvichidikanwa.Zvisinei, kana kubuda kwacho kukaramba kuchiitika, pombi kana kuti fitting ingada kuchinjwa kugadzirisa dambudziko racho.
Zvinoenderana nechigadzirwa.Semuyenzaniso, chisimbiso chakapfava hachimboomese zvachose, saka chinoshingirira kuzunguza kana kudzvanywa shanduko.
Izvo zvinoenderana nemhando, asi iwe unofanirwa kugara uchitanga nekuchenesa tambo.Iyo PTFE tepi inoiswa clockwise kune yechirume shinda.Mushure mekutenderera katatu kana mana, bvisa uye uise mugororo.Pipe lubricant inowanzoiswa kune tambo dzekunze.
