I-tack yokuqala yeAbabukeli kunye nezityholoIbhekisa kubuchule bokunamathela okanye itywina ukuya kwi-Bond ukuya kumhlaba wokuqhawuka, ngaphambi kokuba kuphiliso olubonakalayo okanye isenzeka. Le ndawo ibaluleke kakhulu kwizicelo ezininzi, njengoko igqiba ukuba unamathela kangakanani na ukubambelela ngokudibeneyo ngokukhawuleza emva kwesicelo.
Nazi ezinye iindawo eziphambili malunga ne-tack yokuqala:
Ukubaluleka kokuqala kweTack
I-bonding kwangoko:Isitayile sokuqala esiphezulu sivumela ukuba unamathele kwangoko kwizicelo apho iinxalenye kufuneka zibanjelwe kwindawo yendibano okanye ekumpoleni.
Ukuphatha kunye nokuma:I-tack elungileyo yokuqala inceda ukubeka izinto ngokuchanekileyo ngaphandle komngcipheko wazo otyibilikayo okanye ohamba phambi konyango olunamathela ngokupheleleyo.
Ixesha elifanelekileyo:Iimveliso ezinomxholo wokuqala ophakamileyo unokuncitshiswa kwixesha lendibano, njengoko befuna ukubekwa okanye inkxaso engaphantsi kwenkqubo yonyango.
Izinto ezichaphazela i-tack yokuqala
I-Viskosity:I-viscosity yeSuper Bondokanye itywina linokuphembelela amandla alo okumanzisa umphezulu kwaye wenze iqhina lokuqala. Izixhobo ze-viscofity eziphantsi zihlala zine-tack yokuqala.
Amandla omphezulu:Amandla omphezulu wemimandla ebhabha idlala indima ebalulekileyo. Iindawo eziphakamileyo zamandla (njengezinyithi) zihlala zivumela ukuba ube nokunamathela okungcono kunendawo ephantsi yamandla (njengeplastiki).
Ubushushu kunye nokufuma:Iimeko zendalo esingqongileyo zinokuchaphazela ukusebenza kwezifo. Amaqondo obushushu aphezulu anokuphucula i-tack, ngelixa umswakama unganceda okanye uthintele ububi kuxhomekeka kwi chemistry.
Indlela yokunyanga:Uhlobo lwendlela yokunyanga (umz. Abanye abantu abadala banokufuna inqanaba elithile lokufuma okanye ubushushu ukuze kuphuhliswe i-tack.
Ukuvavanya i-tack yokuqala
Uvavanyo lwe-peel:Indlela eqhelekileyo yokuvavanya i-tack yokuqala luvavanyo lwe-PEEL, apho umtya wokunamathela ugqobhozwa kwindawo enkulu emva koko wakhutshwa ukuze alingane amandla afunekayo ukuze ahlukane.
Uvavanyo lwe-Shear:LeI-Bound eyomeleleyo yelwandleImilinganiselo yovavanyo amandla okunamathela kukuxhathisa amandla okutsala xa amanye amantshontsho adityaniswe kunye.
Uvavanyo lweTack: Iindlela ezithile zovavanyo lweTack, ezinje ngo "uvavanyo lweMinwe," zinokusetyenziselwa ukuvavanya ukuba indlela ezinamathela kuzo kumphezulu emva kokuba isicelo.
Izicelo
Ulwakhiwo:Amadlala nge-teeckies yokuqala ephakamileyo ihlala isetyenziswa ekwakhiweni kweephaneli, iithayile, kunye nezinye izinto ezifunekayo kwangoko.
I-AutoMotive:Kwizicelo zemoto, amachaphaza asetyenziselwa izixhobo zokuboleka ezifuna ukubambelela ngokuchanekileyo ngexesha lendibano.
Ukupakisha:Ukupakisha, i-tack yokuqala ibalulekile ekuqinisekiseni ukuba amatywina abambe ngexesha lezothutho kunye nokugcinwa.
Eyona nto inamathele kakhulu kwilitye lendalo
I-Junbond ilungisa yonke iTack ephezuluI-Super eyomeleleyo ye-boullI-super eyomeleleyo kwaye inamathele nge-teack ephezulu kunye namandla esiphelo (400kg / 10cm²). Ingasetyenziselwa ukutywina kwezinto ezahlukeneyo zokudibana kunye nezinto zenqwanqwa ukufezekisa ukusebenza kakuhle kunye nokutywina kweyona ndawo iphambili kunye ne-porous ye-porous. Imveliso iqulethe iarhente ngokufanelekileyo.
