Emkhakheni wokuhlobisa izakhiwo, itshe belilokhu lithandwa ngenxa yokuthungwa kwalo okuyingqayizivele nokuthungwa okuhle. Kodwa-ke, ngesikhathi sokumba, ukucutshungulwa, ukuthuthwa nokufakwa kwamatshe, ezinye iziphambeko, njengokuqhekeka nezimbobo, azinakugwenywa. Lezi zinkinga azithinti kuphela ubuhle betshe, kodwa futhi zinganciphisa impilo yayo yesevisi. Ukuze sinqobe lezi zinkinga, i-epoxy resin, njengezinto eziphezulu zokusebenza, kancane kancane uye wadlala indima ebalulekile ekucubunguleni nasekuhlobiseni ngamatshe.
Izici ze-epoxy resin kanye nokusebenza kwayo etsheni
I-Epoxy resin iyi-resin ye-thermosetting, isici esiyinhloko ukuthi i-epoxy noma indandatho ye-oxygen iyiqembu eliyinhloko elisebenzayo. Le resin inezinto eziningi ezinhle kakhulu, njengokuzinza okuphezulu kwamakhemikhali, ukumelana nezinga lokushisa eliphezulu, ukufakwa kukagesi kanye nezindleko eziphansi. Ekucutshungulweni kwamatshe, i-epoxy resin isetshenziselwa ikakhulukazi ukulungisa amatshe, ukuqinisa nokwelashwa kwendawo.
Ukulungiswa kwamatshe
Imifantu nemigodi kuvame ukuvela etsheni ngesikhathi sokumba kanye nokucutshungulwa. Izindlela zokulungisa zendabuko zivame ukuba nemiphumela emibi, kuyilapho iglue yokulungisa i-epoxy resin inganikeza isisombululo esiphumelelayo nesihlala njalo. I-low-viscosity, i-hydrophilic elaphekayo ye-epoxy resin yetshe enamathelayo elungisa ubuso, lapho ingxenye A ihlanganisa i-bisphenol A epoxy resin ne-diluted bisphenol A epoxy resin, kanye nengxenye B ihlanganisa i-amine elaphayo kanye ne-ejenti yokwelapha ye-alicyclic amine ezenzele yona.
Le ngcina yokulungisa inezinzuzo zokungafihli obala okungenambala, ukusebenza kahle kokulwa nokuphuzi, isicwebezelisi esiphezulu, ukuvuthwa okuhle, njll. Ingakwazi ukuhlangabezana nezidingo zokulungiswa kwamatshe nokuqiniswa ngemva kokuphulukisa ekamelweni lokushisa noma ukushisa, futhi inobungani bemvelo, ayinabo ubuthi, futhi cishe ayinakuguquguquka.
Ukuqinisa amatshe
Kwamanye amatshe amakhulu noma amatshe asetshenziswa ngezikhathi ezikhethekile, ukwelashwa kokuqinisa kuyadingeka ukuze kuqinisekiswe ukuphepha nokuzinza kwawo. Ama-adhesive e-epoxy resin alungele ukuqinisa amatshe ngenxa yokunamathela kwawo okuhle kakhulu namandla emishini. Uma kuqhathaniswa nezinamatheliso ze-polyester ezingagcwalisiwe zendabuko, izinto zokunamathela ze-epoxy resin zinokushwabana okuncane kanye nokumelana nokuguga okungcono ngemva kokwelashwa. Ukwengeza, ngokuguqulwa, okunamathelayo kwe-epoxy resin kungaqhubeka nokuthuthukisa ukuqina kwabo kanye nesivinini sokuphulukisa ukuze kuhlangatshezwane nezidingo zokubeka ngokushesha kanye nokubopha itshe elomile elilenga embonini yezokwakha.
Ukwelashwa kwendawo yetshe
Ngaphezu kokulungisa nokuqinisa, i-epoxy resin ingasetshenziselwa ukwelashwa kwendawo yamatshe ukuze kuthuthukiswe umphumela wayo wokuhlobisa. Isibonelo, ngokumboza ungqimba lwe-epoxy resin ebusweni betshe, ukucwebezela nokumelana nokugqoka kwetshe kungathuthukiswa, kuyilapho kudlala indima yokungangeni kwamanzi kanye ne-anti-fouling. Le ndlela yokwelapha ebusweni ayivikeli nje itshe kuphela, kodwa futhi yenza kube kuhle kakhulu ngokubukeka.
Izinzuzo zemakethe zemikhiqizo yamatshe e-epoxy resin
Ukusebenza kwemvelo
Ngokuthuthuka okuqhubekayo kokuqwashisa ngemvelo, abathengi banaka kakhulu ukusebenza kwemvelo kwezinto zokuhlobisa. Ukusetshenziswa kwe-epoxy resin ekusetshenzisweni kwamatshe akukwazi ukunciphisa kuphela ukukhishwa kwe-volatile organic compounds (VOC) ezintweni zokulungisa zendabuko, kodwa futhi kugweme ukusetshenziswa kwamakhemikhali ayingozi emzimbeni womuntu. Imikhiqizo ye-epoxy resin ekhiqizwa i-Veropoxy ihlangabezana nezindinganiso eziqinile zemvelo futhi inikeza abasebenzisi isisombululo sokuhlobisa esiluhlaza nesinempilo.
Umphumela wokuhlobisa
I-epoxy resin ingahlanganiswa ngokuphelele netshe, elingakwazi ukulungisa kuphela amaphutha etshe, kodwa futhi lithuthukise ubuhle bayo bemvelo. Ngezinqubo ezikhethekile namafomula, i-epoxy resin ingalingisa ukuthungwa kwamatshe okuhlukahlukene nemibala ukuze kwakhe imiphumela yokuhlobisa eyingqayizivele. Isibonelo, iphansi le-epoxy elinokuthungwa kwetshe lemvelo lingaveza ukuthungwa kwetshe okungokoqobo ngokushumeka imigqa yokuthungwa nemicu kasilika ku-epoxy putty coating, inikeze inketho yenoveli yokuhlobisa phansi.
Izinzuzo zomnotho
Nakuba intengo yemikhiqizo ye-epoxy iphakeme kakhulu, izinzuzo zayo zezomnotho zibalulekile ngokuhamba kwesikhathi. Njengoba i-epoxy resin ingathuthukisa ngempumelelo impilo yesevisi kanye nomphumela wokuhlobisa wetshe, inciphisa imvamisa yokushintshwa kwamatshe kanye nezindleko zokunakekela. Ngaphezu kwalokho, inqubo yokwakha ye-epoxy resin ilula, enganciphisa umjikelezo wokwakha futhi inciphise izindleko zabasebenzi.
Amaphuzu okwakhiwa kwemikhiqizo yamatshe e-epoxy resin
Ukwelashwa kwendawo
Ngaphambi kokwakhiwa, indawo yamatshe idinga ukuhlanzwa kahle futhi iphathwe ukuze kuqinisekiswe ukuthi indawo engaphezulu ayinawo amafutha, uthuli nokunye ukungcola. Ngamatshe anemifantu nezimbobo, ukwelashwa kwangaphambili njengokugaya nokuhlanza kufanele kwenziwe kuqala ukuze kuthuthukiswe ukunamathela kwe-epoxy resin.
Isilinganiso sokuxuba
Isilinganiso sokuxuba se-epoxy resin kanye ne-ejenti yokwelapha ibalulekile emphumeleni wokwakha. Imikhiqizo ehlukene ye-epoxy inezidingo ezihlukene zesilinganiso sokuxuba, futhi izisebenzi zokwakha kufanele zilandele ngokuqinile imiyalelo yomkhiqizo. Isibonelo, i-low-viscosity, ingcina yokulungisa amatshe e-epoxy resin ene-hydrophilic elaphekayo inesilinganiso sokuxuba sezingxenye A no-B ka-2.6 kuya ku-3.3:1.
Izimo zokuphulukisa
Ukwelashwa kwe-epoxy resin kudinga izinga lokushisa elithile nesikhathi. Phakathi nenqubo yokwakha, isikhathi sokuphulukisa kufanele sihlelwe ngokunengqondo ngokuvumelana nezinga lokushisa elizungezile nezici zomkhiqizo. Ngokujwayelekile, kuthatha amahora angama-24 kuye kwangama-48 ukuthi i-epoxy resin yelaphe ekamelweni lokushisa, kuyilapho isikhathi sokwelapha singafinyezwa ngaphansi kwezimo zokushisisa.
Ukuhlolwa kwekhwalithi
Ngemuva kokuthi ukwakhiwa kuqediwe, itshe kufanele lihlolwe izinga ukuze kuhlolwe ukuthi ukunamathela, ukucwebezela, ukumelana nokugqoka kanye nezinye izinkomba ze-epoxy resin zihlangabezana nezidingo. Ezingxenyeni ezingahlangabezani nezidingo, kufanele zilungiswe futhi zicutshungulwe ngesikhathi ukuze kuqinisekiswe ikhwalithi yokwakha.
Ukusetshenziswa kwe-epoxy terrazzo ezakhiweni zezentengiselwano ezisezingeni eliphezulu
Kwezinye izakhiwo zezohwebo ezisezingeni eliphezulu, i-epoxy terrazzo ithandwa ngomphumela wayo oyingqayizivele wokuhlobisa nokusebenza okuhle kakhulu. Isibonelo, indawo ephansi yesikhungo sezitolo esaziwayo sisebenzisa i-epoxy terrazzo, esebenzisa i-epoxy resin engancibiliki njenge-binder, exutshwe nama-aggregate okuhlobisa ahlukene, futhi yenziwa ngezinqubo eziningi ezinhle. Le epoxy terrazzo ayinakho nje kuphela ubuhle nokuqina kwetshe, kodwa futhi inezindawo ezingcono zokungangeni manzi kanye nezokunqanda ukungcolisa, ihlinzeka ngesixazululo esikahle sesitezi sezitolo ezinkulu.
Ukusetshenziswa kwe-epoxy resin ekubuyiselweni kwezakhiwo zasendulo
I-epoxy resin nayo idlala indima ebalulekile ekubuyiselweni kwezakhiwo zasendulo. Njengoba izinto zamatshe zezakhiwo zasendulo zivame ukuguga, kunemifantu eminingi kanye nokulimala, futhi izindlela zokulungisa zendabuko zinzima ukufeza imiphumela emihle. I-epoxy resin ingalungisa ngempumelelo lezi ziphambeko ngenkathi igcina ukubukeka kwasekuqaleni kwetshe. Isibonelo, kuphrojekthi yokubuyiselwa kwesakhiwo sasendulo, imikhiqizo ye-epoxy resin ye-Veropoxy yasetshenziselwa ukulungisa ngempumelelo imifantu yamatshe ebusweni besakhiwo, ukubuyisela ubuhle bayo bangaphambili.
Isiphetho
Ukusetshenziswa kwe-epoxy resin ekusetshenzisweni kwamatshe kanye nokuhlobisa kulethe amathuba amasha okuthuthukiswa embonini yamatshe. Ngokulungisa, ukuqiniswa kanye nokwelashwa kwendawo ye-epoxy resin, hhayi nje kuphela ukuthi umphumela wokuhlobisa wetshe ungathuthukiswa, kodwa futhi impilo yayo yesevisi inganwetshwa. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokwanda okuqhubekayo kwemakethe, imikhiqizo yetshe le-epoxy resin izodlala indima ebaluleke kakhulu emkhakheni wokuhlobisa izakhiwo esikhathini esizayo.
Njengebhizinisi lochwepheshe emkhakheni we-epoxy resin, i-Veropoxy izoqhubeka nokuzinikela ocwaningweni nasekuthuthukisweni nasekukhiqizeni imikhiqizo yekhwalithi engcono futhi inikeze izinsizakalo ezingcono kubasebenzisi.
