Izizathu zamaqamu ngexesha lokuvuselela:
Isizathu sokuba amaqamza aveliswa ngexesha lenkqubo yokuxubaepoxy resiniglu kukuba irhasi eyaziswa ngethuba lenkqubo yokuvuselela ivelisa amaqamza. Esinye isizathu yi "cavitation effect" ebangelwa ulwelo olushukunyiswa ngokukhawuleza. Kukho iindidi ezimbini zamaqamza: ezibonakalayo nezingabonakaliyo. Ukusebenzisa i-vacuum degassing kunokuphelisa kuphela amaqamza abonakalayo, kodwa ayisebenzi ekususeni amaqamza amancinci angabonakaliyo emehlweni abantu.
Izizathu zamaqamza ngexesha lokunyanga:
Oku kungenxa yokuba i-epoxy resin iphiliswa yi-polymerization, ekukusabela kweekhemikhali. Ngexesha lokuphendula, amaqamza amancinci kwinkqubo ye-epoxy resin ashushu kwaye anda, kwaye irhasi ayisahambelani nenkqubo ye-epoxy, emva koko iqokelelene ukuvelisa amaqamza amakhulu.
Izinto ezibangela ukuba i-epoxy resin ibe nogwebu:
(1) Iimpawu zeekhemikhali ezingazinzanga
(2) Ukuxuba xa ulungiselela ujiya
(3) Ugwebu emva koqokelelo lwe-thickener
(4) Inkqubo yokukhupha i-slurry
Iingozi ze-epoxy resin enegwebu ngexesha lokuxuba:
(1) Ugwebu lubangela ukuphuphuma kunye nokusetyenziswa okutyebileyo, okuya kuchaphazela nokuphakama komgangatho wolwelo olujongwayo.
(2) Iibhubhu ezibangelwa ukunyanga i-amine yeemolekyuli ziya kuchaphazela ukusebenza kakuhle kolwakhiwo.
(3) Ubukho be "bubbles ezimanzi" buya kubangela i-VCM igesi yesigaba se-polymerization, eveliswa ngokubanzi kwi-kettle yokunamathela.

Indlela yokuphelisa amaqamza omoya?
Iindidi zemveliso ye-ejenti esetyenziswa rhoqo: i-silicone defoaming agents, i-non-silicon defoaming agents, i-polyether defoaming agents, i-oyile ye-mineral defoaming agents, i-high-carbon alcohol defoaming agents, njl.
Xa iqondo lobushushu lisezantsi, iimpawu ezininzi izinto ezingamanzi Utshintsho luya kwenzeka, ngakumbi i-viscosity yezinto ezincamathelayo ezingamanzi ziya kwanda njengoko ubushushu buyancipha.Epoxy resin ab iglu, njengento eqhelekileyo engamanzi, inokwanda okukhulu kwixabiso le-viscosity ngenxa yokuncipha kweqondo lokushisa. Ngoko ke, ngexesha lokusetyenziswa kunye nokusetyenziswa, ama-bubbles anzima ukuphelisa, ukusebenza kwe-flattening kuncitshiswe, kwaye ukwanda kwexesha lokusetyenziswa kunye nexesha lokunyanga akuncedi kwimveliso eqhelekileyo kunye nokulawula. Nangona kunjalo, ngokuqokelelwa kweminyaka emininzi yamava emveliso, siye sashwankathela amava athile aluncedo ukusombulula ngempumelelo kunye nokunciphisa iingxaki ezibangelwa zezi ngxaki zingasentla. Ngokukodwa, kukho ezi ndlela zine zilandelayo:
1. Indlela yokufudumeza indawo yomsebenzi:
Xa iqondo lokushisa kwindawo yomsebenzi lihla ukuya kwi-25 ° C, ukufudumeza okusebenzayo kwendawo yomsebenzi kuyadingeka ukuphakamisa ubushushu kwiqondo lokushisa elilungele ukusebenza kweglue (25 ° C ~ 30 ° C). Kwangaxeshanye, ukufuma komoya okunxulumeneyo kwindawo yomsebenzi kufuneka kugcinwe kwi-70%. okanye ke, de iqondo lobushushu leglu ngokwayo lifane nobushushu be-ambient phambi kokuba iglu isebenze kwaye isetyenziswe ngokufanelekileyo.
Isikhumbuzi esifudumeleyo: Le ndlela yeyona ndlela isebenzayo, kodwa iindleko zokusebenza ziya kuba phezulu, nceda unikele ingqalelo kwi-accounting yeendleko.
2. Indlela yokufudumeza amanzi abilayo:
Ukupholisa kuya kunciphisa ngokuthe ngqo ixabiso le-viscosity yeepoxy resinab glue kwaye uyandise kakhulu. Ukuyifudumeza kwangaphambili ngaphambi kokusebenzisa iglue kuya kwandisa ukushisa kwayo kunye nokunciphisa ixabiso le-viscosity, okwenza kube lula ukuyisebenzisa. Indlela ethile kukubeka yonke ibhotile okanye ibhotile yeglu emanzini abilayo kwaye uyifudumeze malunga neeyure ezi-2 ngaphambi kokuba usebenzise iglue, ukuze ubushushu beglue bufike malunga ne-30 ℃, emva koko uyikhuphe, uyihlukumeze kabini, emva koko ugcine i-glue kwiqondo lokushisa elingekho ngaphantsi kwe-30 ℃ emanzini afudumele kwaye usebenzise ngelixa ufudumeza. Ngethuba lokusetyenziswa, khupha iglue kwaye uyigubungele yonke isiqingatha seyure ukugcina ubushushu kunye nokubunjwa kweglue symmetrical. Kodwa qaphela ngokukodwa ukuba ungavumeli iglue kwibhakethi okanye ibhotile inamathele emanzini, ngaphandle koko kuya kukhokelela kwimiphumo emibi okanye emibi.
Isikhumbuzo esifudumeleyo: Le ndlela ilula, iyonga kwaye iyasebenza, kwaye iindleko kunye nezixhobo zilula. Nangona kunjalo, kukho iingozi ezifihlakeleyo, ekufuneka ziqwalaselwe.
3. Indlela yokufudumeza i-oveni:
Abasebenzisi abaneemeko banokusebenzisa i-epoxy resin ab ukufudumeza iglu a kwi-oveni ngaphambi kokusebenzisa iglu ukunqanda ukudibana ngengozi namanzi. Ilula kakhulu. Indlela ethile kukulungelelanisa ubushushu be-oven ukuya kuma-60 ° C, emva koko ubeke yonke i-barrel okanye ibhotile ye-A glue kwi-oven ukutshisa, ukwenzela ukuba iqondo lokushisa leglue lifike kwi-30 ° C, emva koko uthabathe iglue kwaye uyivuthulule kabini, uze ubeke iglu kwiqondo lokushisa lokuhlengahlengisa kwi-30 ° C phakathi kwe-oven usebenzisa i-glue eshushu kwaye uqaphele ukukhupha iglue malunga neyure. ihlala igcina iqondo lobushushu elilinganayo kunye nezithako
Isikhumbuzi esifudumeleyo: Le ndlela iya kwandisa ixabiso kancinane, kodwa ilula kwaye iyasebenza.
4. Indlela yoncedo ye-arhente yokukhupha amagwebu:
Ukuze kukhawuleziswe ngokwemodareyitha ukususwa amaqamza, unako kwakhona ukuthenga arhente defoaming ekhethekileyo epoxy resin ab-eyongeziweyo iglu, kwaye wongeze iglu kunye nomlinganiselo 3‰ ngaphakathi, indlela ethile; ukongeza ngokuthe ngqo akukho ngaphezu kwe-3% yeglue kwi-A glue evuthayo ngale ndlela ingentla. I-arhente ekhethekileyo yokukhupha amagwebu yeepoxy resin AB iglu, uze udibanise ngokulinganayo kwaye udibanise ne-B glue ukuze uyisebenzise.
