I-tack yokuqala yeanamathela kanye nama-sealantsKubhekiswa emandleni okunamathela noma i-sealant ebophweni kuya engxenyeni engezansi lapho uthintana khona, ngaphambi kokuba kuqale noma yikuphi ukwelashwa okubalulekile noma ukusetha. Le mpahla ibalulekile kwizicelo eziningi, njengoba inquma ukuthi anamathela kuzo zizobamba kahle kangakanani izinto zokwakha ndawonye ngokushesha ngemuva kwesicelo.
Nawa amanye amaphuzu asemqoka mayelana ne-Tack yokuqala:
Ukubaluleka Kokubumba Okuqala
Ukubopha okusheshayo:I-High Initist Tack ivumela ukunamathela ngokushesha, okubalulekile kwizicelo lapho izingxenye zidinga ukuba zibe khona endaweni ngesikhathi somhlangano noma ngokwelapha.
Ukuphatha nokubeka:I-Tack Yokuqala Yokuqala isiza ngezinto zokubeka izinto ngokunembile ngaphandle kwengozi yazo ishelela noma ihamba ngaphambi kokwelashwa okugcwele.
Ukusebenza kahle kwesikhathi:Imikhiqizo ene-High Onitination Tack inganciphisa isikhathi somhlangano, njengoba idinga ukubopha okuncane noma ukusekelwa ngesikhathi senqubo yokwelapha.
Izici ezithinta i-tack yokuqala
I-Viscosity:I-viscosity yesuper bonding adhesivenoma i-sealant ingathonya ikhono layo lokumanzisa indawo futhi yakha isibopho sokuqala. Izinto zokwakha ezisezingeni eliphansi zivame ukuba ne-tack yokuqala engcono.
Amandla angaphezulu:Amandla angaphezulu kwezigatshana ababoshelwe abadlala indima ebalulekile. I-High-Energy Surfaces (njengezinsimbi) ngokuvamile zivumela ukunamathela okungcono kunezindawo eziphansi zamandla (njengeziplasikhi).
Lokushisa kanye nomswakama:Izimo zezemvelo zingathinta ukusebenza kwezinamathela. Amazinga okushisa aphezulu angaqhakambisa i-tack, ngenkathi umswakama angasiza noma avimbele ukunamathela kuye ngokuthi ku-adhesive chemistry.
I-Purling Mechanism:Uhlobo lwendlela yokulapha (isib. Ukwelashwa komswakama, ukwelapha ukushisa, i-UV-welapha) kungathonya i-tack yokuqala. Amanye ama-adhesives angadinga izinga elithile umswakama noma ukushisa ukuthuthukisa i-tack.
Ukuhlola i-Tack yokuqala
Ukuhlolwa kwe-peel:Indlela ejwayelekile yokuhlola iTack Fination inguhlolo lwe-peel, lapho isigaxa sokunamathela siboshelwe khona esihlokweni sabe sesidonsa ukukala amandla adingekayo ukuzehlukanisa.
Ukuhlolwa kwe-Shear:LeliI-Bonding Sealant eqinileUkuhlolwa kulinganisa amandla okunamathela okumelana nemikhosi eshelelayo lapho ama-substrates amabili ahlanganiswe ndawonye.
Ukuhlolwa kwe-Tack: Izindlela ezithile zokuhlola ze-Tack Testing, njengokuthi "ukuhlolwa komunwe," kungasetshenziswa ukuhlola ukuthi izinduku ezinamathela ebusweni ngokushesha nje ngemuva kwesicelo.
Izinja
Ukwakha:Ukunamathela nge-tack ephezulu yokuqala kuvame ukusetshenziswa ekwakheni amaphaneli eBonding, amathayili nezinye izinto lapho kubanjwa khona ngokushesha.
Izithuthi:Ezicelo zezimoto, anama-adhesives asetshenziselwa izingxenye zokubopha okudinga ukubekwa ngokunembayo ngesikhathi umhlangano.
Ukupakishwa:Ekupakisheni, i-tack yokuqala ibalulekile ekuqinisekiseni ukuthi izimpawu zibambe ngesikhathi sokuhamba nokugcinwa.
Ukunamathelisa okuhle ngetshe lemvelo
Xebond filisa yonke i-tack ephezuluSuper oqinile bonding sealantI-Super Strong Sealant futhi inamathela nge-Tack ephezulu yokuqala kanye namandla okugcina (400kg / 10cm²). Ingasetshenziswa ukubeka amalunga ahlukahlukene nezinto zokubopha ukufezekisa ukubopha okuguquguqukayo nokubekwa uphawu cishe kunoma iyiphi indawo ye-porous nengeyona ye-porous.Imkhiqizo iqukethe ama-antifungal agents avimbela ukukhula ngenkani.
