Ngubani i-Polyester Resin?
I-Polyester resin yichasenathi elithile lapho lehlukene ngokwesintsho esebenzisa kakhulu. Ngoba kukho ngezimpondo zakhe nokuthi akuyiphi inqanawa, yilokhu olunqamene kunye neziqhaza ezininzi zisebenzisa. Ngenxa yalokho izinto ezibomvu, siyasebenzisa ukuba zikhuphe imibhalo, amaxhovha wecar, izibote nezinto ezinye. Kodwa, ngokulandelayo, ukuze sikwenze i-polyester resin usebenza khona, siphumelela isicatathu.
Ngubani Unxumo?
Isicatathu sesikhefumayo sifundiswa njengeyonto engazenza imibuzo yokugcwalisa okanye. Yisihlobo lokuhlola lokuhlola, kodwa ayiqhuba ngaso ngokwesobizo kulesobizo. Isicatathu silayishwa kwi-polyester resin ukuze sisukele umthakathi woresibayiso wesiqephu. Kufuneka lokhu ngoba kusetyenziswa ukuba isiqephu sigqweme ukusebenza. Ukuseta isicatathu esingezwe, isiqephu asizange sikwenzela ukucure kakhulu. Lokhu lingazange libaleke ngokushesha okanye alulekise ngokubanjwa kwezinto ezilandelayo, okungafunekayo ukuba ubude bethu bekhawuleze.
Ukukhetha Isicatathu Esingezwe
Kwaye ukuba isibhendulo siphakeme ngokwesintsho, kufuneka sikhethe amacalisiteli ephendulekileyo yomsebenzi. Amacalisiteli angahlukileyo ngezinto ezifanayo. Kodwa, zonke izinto zakho zaziphumelela ukuthi khathale umthengi wokubhala kwisibhendulo esikhathini. Zingaphandle zihlelwa ukusuka kwezindlela ezidingekayo ezitholakalo lwenqanawa lokuthi lisibhendulo sikhulu kunye nokungabhedlisele. Lento ithola isenzo sezethemba singahlanganisa ukubona ukuthi siyazi ukuthi singayiphihlisa ngazo imisebenzi yakho.
Ukubophelela Izinto Nemisingo Yesisibhendulo
Siyazi ngaphandle ukuba zithi lokhu othandwa kuhle kwi-resin xa siyikhetha isibhedlela. Ngokushesha, uma sithanda ukuthi i-resin iyiphumele ekufaneleyo ngephandle - njengesiyele esihlanganyeliwe ngendawo yokugcina - sizokukhetha isibhedlela esemigqibeleyo kunye no-cobalt naphthenate. Le sibhedlela isehlise ukwenzela ukuba i-resin iyiphumele ekufaneleyo ngephandle. Ngakwesobukele, ukusuka ukuba i-resin isetyenziswa, sinezona amagama angamathanga njenge-benzoyl peroxide. I-resin elisetyenziswa ngesibhedlela lisetyenziswa kakhulu kumyinge yamanye amasayensi. Ukukhetha kwe-sibhedlela esingezwe ususebenzisa ukubuyiselwa kwe-ncwadi nekuphumelela kwe-resin ukuya kuqinisekisa ukuba kube ngokuzenzakalelayo kulesi sicwangciso.

Ukuyongeza umphathisi yile nto elineengxenyeni ngokubanzi xa uhlala ukuthi uze ubolise i-resin yesipholisetha. Kuneempahathi ezinakanyiswayo aziphathiswa kwi-resin ukuba zibolise ngokukhawulezeka kunye neentsha. Ngokulandelayo, umphathisi oluthiwe njengesi-triethylenediamine (TEDA) ungavamile kwi-resin ukuvamisa isandla. Yiloko ukuba le nto engqondweni ayiqhelekanga kunye nokuhlola. Izinyathelo ezimbini — njenge-dibenzoyl peroxide, yinto engepe enkulungileyo — ziziphathiswe kwindawo yokugcina ukuba leli resin libolise kakhulu kunye nokuphindezelwa nge-impact. Iimpahathi ezikhethwayo zivamisa idilesi yokuqala kwe-resin yesipholisetha ngokusho ukuba kube khona kwiseveni esingabangako.
Ngubani Amaphathisi Angakho Ngenxa Yokuba Zineengxenyeni
Ngaphandle kwezinto, ukusebenzisa amacatalisi ethunyelwe ngokubhekisisa kunokuthola ukuba uqondileyo nokusetyenziswa kwesoresi yesoresi lepoliestera. Ukulungisa lowo sihlalo sasesoresi, kunye nokuhlala phakathi komphilo wethu yokuthi ashiwo, kukho ngenxa yoko. Lolu ncwadi layisebenza ukukhusela ukuba zonke izinto ezinethuthukiswa ezithunyelwe ngamapoliestera esoresi, njengemali, amanye amaxhobo, amabhayide, amaxesha, kunye neziqhaza zomthombo ezifanayo, zibuyelekile ngokubheka ukuthi amacatalisi angavumelelwe ngempumelelo. Lingishi yiindlela efanelekile eyenza ukuphucula kokuthi amacatalisi amahusha amathathwe ukumelana namandla okanye ndawonye. Amacatalisi amadifasini aphantsi kunezinye izigomo ezidingekayo, kunye nokuhlawula umthetho wesoresi. Ngaphezulu, isoresi lesopoliestera lingabuyelekile ngokubheka ukuthi lizofundiswa ngazo zonke izilimi zezintsimbi kunye nokuthi Lingishi yinketho elikhoyo ukwenza lokhu ngokwesiphumo sokugcina nokuziphatha.
