Uvavanyo lomgangatho wengca eyenziweyo lubandakanya ntoni?Kukho imigangatho emibini ephambili yovavanyo lomgangatho wengca eyenziweyo, oko kukuthi imigangatho yomgangatho wemveliso yengca eyenziweyo kunye nemigangatho yomgangatho wendawo yokutyibiliza ingca eyenziweyo. Imigangatho yemveliso ibandakanya umgangatho wefayibha yengca eyenziweyo kunye nemigangatho yokuhlolwa kwezinto ezibonakalayo zengca eyenziweyo; imigangatho yendawo ibandakanya ukuthamba kwendawo, ukuthambekela, ulawulo lobungakanani bendawo kunye neminye imigangatho.
Imigangatho yokuhlolwa komgangatho wemveliso: Iintambo zengca ezenziweyo zenziwe ngezinto ze-PP okanye ze-PE. Iintambo zengca kufuneka zihlolwe ziiarhente zovavanyo ezingqongqo. Abavelisi beengca ezenziweyo kufuneka babe nesatifikethi sokukhusela umlilo senqanaba lesibini le-SGS, isatifikethi sezinto ezinobuthi neziyingozi, isiqinisekiso sokulwa nokugqwala, isiqinisekiso esingagugiyo, njl.njl.; kwangaxeshanye, ingca. I-glue esetyenziswa ezantsi ikwachaphazela umgangatho wengca eyenziweyo, kwaye i-glue kufuneka ibe nesatifikethi sokhuseleko kunye nokhuseleko lokusingqongileyo.
Imigangatho yokuhlolwa kwezinto ezibonakalayo ezisemgangathweni: oko kukuthi, ukolulwa kwefayibha yengca eyenziweyo, uvavanyo lokulwa nokwaluphala, umbala wengca eyenziweyo kunye neminye imigangatho yovavanyo lwengca eyenziweyo. Ukwandiswa kokutsalwa kwentambo yengca eyenziweyo kwicala elide akufuneki kube ngaphantsi kwe-15% kwaye ukwandiswa okunqamlezileyo akufanele kube ngaphantsi kwe-8%; umgangatho wamandla okukrazula kwengca eyenziweyo kufuneka ube ubuncinane yi-30KN/m kwicala elide kwaye kungabi ngaphantsi kwe-25KN/m kwicala elinqamlezileyo; Izinga lokwandiswa kunye namandla okukrazula kwengca ahlangabezana nemigangatho, kwaye umgangatho wengca uyaphuculwa ngakumbi.
Imigangatho yovavanyo lombala: Umbala wengca kufuneka uvavanywe ukuze ubone ukuba awuchasani ne-sulfuric acid. Khetha ubungakanani obufanelekileyo besampulu yengca yokwenziwa kwaye uyifake kwi-80% ye-sulfuric acid kangangeentsuku ezi-3. Emva kweentsuku ezintathu, jonga umbala wengca. Ukuba akukho tshintsho kumbala wengca yokwenziwa, kuya kugqitywa ukuba umbala wengca yokwenziwa uyahlangabezana nemigangatho yomgangatho wengca yokwenziwa.
Ukongeza, ingca eyenziweyo kufuneka ivavanywe ukuguga. Emva kovavanyo lokuguga, amandla okutsalwa kwengca afunyaniswa ukuba ubuncinane yi-16 MPa kwicala elide kwaye kungabi ngaphantsi kwe-8 MPa kwicala elinqamlezileyo; amandla okukrazula angabi ngaphantsi kwe-25 KN/m kwicala elide kunye ne-20 KN/m kwicala elinqamlezileyo. m. Kwangaxeshanye, umgangatho wengca eyenziweyo kufuneka ube nemigangatho yokuthintela umlilo. Ukuthintela umlilo, khetha ubungakanani obufanelekileyo beesampuli zengca kwaye uzizalise ngesanti encinci kwi-25–80 kg/㎡ yokuvavanya. Ukuba ububanzi bendawo etshayo bungaphakathi kwe-5 cm, yi-grade 1, kwaye ingca eyenziweyo ayitshi. Isondo sisemgangathweni.
Umgangatho wokuhlolwa komgangatho wokugawulwa kweendawo kukulawula ukuba indawo ithe tyaba kangakanani ukuya kwi-10mm, kwaye usebenzise umgca omncinci we-3m ukulinganisa ukuthintela iimpazamo ezinkulu; xa ugawulwa ingca, qinisekisa ukuba indawo ithambekele ngaphakathi kwe-1%, kwaye ulinganise ngenqanaba; indawo ithambekele ilawulwa, Ukuze ingca ikwazi ukufunxa amanzi kakuhle. Kwangaxeshanye, impazamo yobukhulu bobude nobubanzi bentsimi yengca eyenziweyo ilawulwa ukuya kwi-10 mm. Sebenzisa irula ukulinganisa kwaye ugcine impazamo iphantsi kangangoko.
Iimveliso zengca yokwenziwa zinokudityaniswa kuphela kwindawo egayiweyo ngokuqonda kakuhle iparameter nganye.Imveliso yotshani eyenziweyoizalathisi zisebenza kakuhle kakhulu kwaye ziyahlangabezana nemigangatho. Ukuba iimfuno zokugawulwa kwendawo azihlangabezani nemigangatho, ingca eyenziweyo ayiyi kukwazi ukubonisa ixabiso layo elifanelekileyo lokusetyenziswa. Ke ngoko, imigangatho yomgangatho ophezulu yengca eyenziweyo ifuna ukuhlanganiswa komgangatho wemveliso kunye nemigangatho yesiza, zombini ezi zinto ziyimfuneko.
