I-foam iyi konke, kusuka kwezincushini zokuziphatha ezinomphela kwi-couch yakho ukuya kwezinto zokuvikela zokuthengiselwa ngaphandle kwesikhala. Kodwa ungaxhathisekanga ukuthi yintoni eyenza i-foam ibe nomphela, ibe yimnandi, okanye ibe yinkululeko yokuhlisa ubomi? Konke kuyaphuma kwezinto eziqhelekileyo. Kwi-SANYING, sisebenza nezinto ezimbili eziphambili: i-polyol kunye ne-isocyanate. Khangelani zibe njengamabrikhedi we-LEGO esibizana ngazo ngendlela ethile ukuze sakhelwe izithunzi zika-foam. I-polyol isenzi indawo yomkhakha wokuqala, kunye nokuba kunezithunzi ezininzi. I-isocyanate yisilungisi, kunye nokuthi ukukhanya kwayo kubanzi kakhulu ukuthi yintoni eyenza i-structure yaka-foam. Ukufumana umlinganiselo othile kuyisisekelo sokwenza i-foam esifuna ukusebenza ngayo ngokupheleleyo. Sihlala sibhalisa umxholo omuhle ukwenza i-foam enobunzima obuhle kubazali.
Ukuthi i-Isocyanate Reactivity Inentla Yintoni Yokugcina I-Foam Yokugcina Ngokwemigqa
Xa kuchazwa ukwenza izifo ezinkulu zokuthenga kwamakhaya amaningi, ukuthi isocyanate ithathe ubude bani ukuphinda kwi-flexibility. Yithandaza ukuba uyakha ngamaphepha amaningi amakhulu ngokukhawuleza. Ukuba umthwalo (isocyanate) uphinde ngokukhawuleza, uyakufumana into engeyona mthwalo. Kodwa ukuba uphinde ngokucinezela, isistraktcha singakwazi ukubendela ngokukhawuleza. Lokho kuyakhiwa ngokufanayo nesifo. e isocyanate (MDI) ziyiziphi, ziyenza ukuthi umsindo uqale ukuzalwa kancane kwaye ukuhamba ngokukhawuleza, kunjalo okuhle ukusetyenziswa kwezinto ezilungileyo. Ezinye zibhekisele kude, zivumela umsindo uze uqale ukuzalwa ngokucindezela ukuze ukuhambisana nokubuyela emva. Le msindo eyenziwe ngokufunyanwa yinkimbinkimbi iphelele yomthwalo noma amaphetha, ibonakala njengomthwalo wokuqala xa usihlale. Kwi-SANYING, siyakhetha ngokuchanekileyo i-isocyanate yokusebenza, ikakhulu xa kubizwa izikreli ezinkulu. Ukuba umkhangeli ufuna ukuthi umsindo uqiniseke kwaye ubuyele emva, sikhetha leyo eyincindezela. Ukuba ufuna ukuthi uqiniseke izinto ezenzima, sikhetha leyo eyikhawuleza. Sibonakalisa njengoko sibhiza, isikhathi sokubhiza kwe-isocyanate sibonakalisa indlela yokuhamba kwe-msindo. Siyafunda ukuthi izinguquko ezincinci zinokwenza izinguquko ezenzima kumthwalo, ikakhulu xa kubizwa izikreli ezenzima. Ngamanye amaxesha, sibhala kwaye sikhetha ukuthi sibe nenqaku elihle. Akukho nje ukukhawuleza, kodwa ukulawula inkqubo ukuze ngokugcina umsindo wonke uyafanana nento umkhangeli ufuna. Oku kwenza ukuthi umsindo wase-SANYING uyabakwa ngokupheleleyo, ngokuzenzakalela noma ngokuzenzakalela, kusuka kwe-reactivity. Sibona izinto ezingavumelekanga ukuba sikhethile ngokungafanelekileyo, njengoko kuzoba kubhakha kwaye kuzoba kubhakha kwaye akukho mthwalo wokuvumela. Ngoko ke sifokusela apha.
Umbono we-Polyol kwaye umsindo wokuvumela
I-Polyol njengomqondo wokuphakama kwe-foam, isithembiso sakho sisebenza kakhulu ekuvimbeni kwemvelo, ukugcina umoya omkhulu okanye omncane ukuze asondele. Khumbula i-sponges: ezinye zinezikhala ezingaphezulu, ezinye zinezikhala eziphakade ezincinci. Iziphakade ezincinci zibhekisa umoya ngokupheleleyo, njengamaphela aphinda akubhekisi umthwalo. Ngoko ke i-polyol engeza izikhala eziphakade ezincinci ziyisilika esihle sokuvimba kwi-refrigerators okanye kwiindawo zokuhlala. Ii-polyol ezahlukeneyo zinezinguqulelo zokuphakama, ziyahlukana ngokwezikhala. Ezinye zizindlela ezinde zokuzigqibela ziyenza izikhala eziphakade, ziyisilika esihle kodwa akuvimbi. Ezinye zizindlela ezincinci zokuzigqibela ziyenza izikhala eziphakade ezinconywa, oko sinokuthanda ukuvimba ngokupheleleyo. Kwi-SANYING siya khetha i-polyol ngokunye nesidingo. Ukuba i-freezer iyagcina intshiso emhlabeni yomhla omkhulu, izikhala eziphakade ezinconywa ziyakunciphisa umthwalo. Ukuba umoya uyakusiza ukufihla, siyasebenzisa i-polyol enye. Njengoko kuyisilika yendawo yokuhlala, akukho mfanekiso oyo oyikufanayo konke kwindawo, ukhetho lwe-polyol liyisalathiso esikhundlazayo. I-polyol esihle iyakunciphisa imali yomthwalo. Ukuphakama kwezinto zokuchaza kuyakusiza kakhulu, ezinye ziyakusiza ukungavimbi umlambo wamafuta. Kubalulekile, kodwa isithembiso se-polyol siyisalathiso esikhundlazayo sokuvimba ngokupheleleyo. Siyajonga amanye amathuba okwenza izikhala eziphakade ezinconywa ukuvimba ngokupheleleyo.
Amaphumo Okukhokha Ngamakhulu
Kwinkqubo yokuthengiselwa ngamaphepha, usizo olukhulu kumakhasi, ubunzima obungakanani. Umrengeti udinga ukuba yonke imibini ibe nenkxaso eyodwa, okanye kuzoba kunye nesiphumo esingavumelekanga sokuphatha. Ngoko ke sifaka isilisa polyol isocyanate sikhethe ngokucacileyo, sibophelela ukuziphatha kwemithombo ngokupheleleyo. Ngokufanayo nezikhweni zokuphatha iziciko zokuphatha ukusuka kwezincinane kwiizikhweni ezinkulu. Kuyasebenza ngokulula kakhulu, ukuthenga ngamaphepha kufuna ukuthenga ukusuka kwezinto eziphambili. Siyenzeka ngokulinganayo, sisebenzisa iimpahla ngokulinganayo, kubeka ubuncinane bokugcina, amagqabi akhawuleza. Ngamanye amaxesha ipolyol engeyona engeyona encinane eyenza isebenza. Sibalance ubukhulu nobunzima. Abarenjisi abahlukahlukene badinga ukuthengiselwa okanye iindlu, ngoko ke sinika isigaba sefoams esinazo iziphumo zokuphatha. Iiminyaka yezifundo zisiza ukuthengiselwa kube lula kakhulu, nokubhala ubunzima obungabandakanyi. Sibhala ubuhlobo, sizisusa ukuba baphume. Xa baphatha i-foam yethu, bakhula umsebenzi wabo. Ngoko ke isizathu sesizimele konke, kusuka kwekhaya kuya kudeliver.
Isiqhelo se-Isocyanate kumaqhubi wezindustria
Yithanda i-LEGO, iibhrikhi zomthwalo ne-isocyanate. Umlinganiselo njengomthwalo, ubani ubuninzi be-isocyanate kumthwalo. Kwi-SANYING kuyimpendulo enkulu. Kukhulu kakhulu, i-foam ibe yinkulu, ibe yinkulu, ibe yinkulu, ibe yinkulu. Kuncinci kakhulu, ibe yincinci, ibe yincinci, ayikho umfanekiso. Abathengi bazi ngoko kunokuthintela ukusebenza. Umlinganiselo omuhle uwenza i-foam ipheleleyo yokuphakama, ukuchitha, okanye ukudlala. Siyihlawula ukuba ibe yinkulu, ibe yinkulu, ibe yinkulu. Umphumela omuhle wokulinganisa uyisiphumo esihle se-foam sokufuna. Ukuzilungiselela kumthwalo kusiza i-SANYING ukuba ibe yinkulu.
Ukuthenga kwe-Polyol & Isocyanate
Ngokufana nokubeka, kufuneka kunezinkolo ezinhle nezinkolo zokubeka ukusuka emaqaleni. Kwi-foam, i-polyol ne- isobhayisayenti yePolyurethane polyol . Ukuthenga kufuna indawo enkulu, ubuninzi obuhle. Izinto ezingavumelekile ziyenza i-foam engavumelekile, njengokubeka kwemithwalo yokuqala. I-SANYING ithenga abasendaweni ababili, abaziwa ngobuninzi obuhle, ukuthumela kubalulekile. Konke okuthengwa kuyafana nokuthengwa. Lokhu kusiza ukubonisa ukuthi i-foam ibe yinkulu. Umqondo ongapheliyo, umsakazo. Ukukhetha ngokweminyaka kusiza ukuthi abathengi bafanele, ukusebenza ngokuvumelekile.
Umlinganiselo we-Isocyanate ku-Polyol kwiindustri
Buya kwi-LEGOs, index recipe, isilinganiso sesilinganiso sokulinganisa ngokwesibalo njenge-mehlathi, isukari kwi-dough. Kwi-industri, sibalulekile. Iziseko ezihlukahlukene zidinga izifoam ezihlukahlukene. Isitayela sesiyele sisobala, sikhula kakhulu, sibuyele kumthwalo wakhe. Ukubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala kwezindawo zokubhala kuzikhuba zokubhala k......
