Xa sisebenzisa i-SANYING, njenge-foam okanye amakhulu, kubakho umxholo wemithombo yezinto eziqhelekileyo. Kuyisibonelo somzimba ombili ophumelelayo kwaye oya kwenza into entsha neyinkulu. Le mix inebhloko ezimbini: i-polyols kunye ne-isocyanates. I-polyols zinjongo zokwakha, zinezinye izandla ezilungileyo ukulinkisa. I-isocyanates ziyizilinkisi, zixhuma lezi zandla. Xa ziphumelela kusobala, zenza izihlangu ezingakanani. Lezi zihlangu zenza isiseko se-polyurethanes. Ngokufana nokuxhuma kwe-LEGO, kodwa zingakanani kunye nezivela ngaphandle. Le ndawo yokuziphatha iyakwenza i-polyurethane ibalulekile kakhulu, kusukela kumapad angcwele kwiintsontsi zomkhosi ozikhulu. Sibe nesiqiniseko esikhulu ekutheni le ndawo iyakwenza ukuba iintonga zethu zibe nzima.

Ukuthenga Umxholo we-Polyol-Isocyanate Ukufuna iintonga Ezinzima

Ku-SANYING, ukwenza izinto ezimbi zokusebenzisa i-polyurethane kuthetha ukwazi ukubhekisele kwi-mix esithile se-polyols ne-isocyanates. Yibhali i-polyols njengezinye iintloko, ezisukwe ukuphanda. Lezi "intloko" ziyiizigqabi ze-hydroxyl, ozikwabizwa ngazo i-polyol. Ziyiziqhaza eziphambili ezisukwe ukuphanda umntu othile. I-Isocyanates ziyizinto eziphambili, nezigqabi ze-isocyanate zisukwe ukuphanda lezi ziqhaza ze-hydroxyl. Xa polyether polyol phumelela i-isocyanate, indlela enobunzulu! I-hydroxyl kusuka ku-polyol kunye ne-group ye-isocyanate zibondi ngokupheleleyo, zenza i-urethane link. Iqinisekile njengoko kukho umthwalo wemolekyuli. Kodwa kubhekwe phambili ngoba i-polyols ziyisiseko zine-hydroxyl eziningi, kwaye i-isocyanates ziyisiseko zineziqondo eziningi. Ngoko ke i-polyol enye inokubondela i-isocyanates eziningi, zenza i-chain ezide okanye i-branches. Lezi zichain zisetha izinto zomfanekiso. I-chain ezide nezilungile zenza izinto eziphakathi, kwaye ezilungileyo zenza izinto eziphakathi. SANYING ibheka ngokucacile iithayipi esisebenzisa. I-polyol ene-hydroxyl eziningi isenzeka ngokukhawuleza, isenza izinto eziphakathi. I-isocyanate eneziqondo eziningi inceda ukuphakamisa ubunzulu. Ngamanye amaxesha sifaka iinkcukacha zokuchelela ukuzisa ukusebenza. Okanye izinto zokuvikela kwinkabi. Umoya uphakade unobunzulu kakhulu. Ukuba kude kakhulu kusebenza ngokukhawuleza nangokwenza iziphulo, ukuba kuncinci kusebenza ngokuchaphazela. Ngoko ke ukulawula umoya kusetha isikhathi. Isilinganiso sisebenzisa sisixhobo, ukuba kune-polyol kakhulu kusenza izinto eziphakathi, ukuba kune-isocyanate kakhulu kuyasimfuna ukuvikela. Ukulinganiswa njengoko kufuneka kusetyenziswa. Indlela yam kwi-factory yachaza ukuba izinguqulo ezincinci zinokwenza iziphulo ezikhulu, njengoko kungaba ngokwenza i-cake engafanelekanga. Ngoko ke ukulawula ubunzulu baka-SANYING bubalulekile kakhulu. Sisondela i-polyols ne-isocyanates ezipheleleyo ukwenza ukusebenza okupheleleyo.

Izinto eziphambili kwi-Polyol-Isocyanate Chem esetyenziswa kushishino

Kuba uSANYING, uyazi i-polyol isocyanate chem hayi nje ukwenza imveliso, kodwa ilungile emsebenzini. Cinga nje into efunekayo: yomelele kumatshini, okanye ibhetyebhetye ukuze ithintele ukubetha. Iintlobo zeepolyols isocyanate qhuba oku. Iipolyether polyols zikhuselekile ngakumbi emanzini, ipolyester yomelele ngakumbi kwioyile. Khetha ngokusekelwe ekusetyenzisweni, njenge polyether yombhobho omanzi. Ii-isocyanates ezifana ne-TDI MDI. I-MDI yokugquma i-foam eqinileyo, i-TDI eguquguqukayo yezihlalo. Umlinganiselo, i-stoichiometry, ibalulekile kufuphi ne-1: 1 ukuze kuphenduleke ngokupheleleyo. I-isocyanate eninzi kakhulu ingxaki yokhuseleko, ipolyol enobuthathaka kakhulu. Isitshixo seTemp, ukufudumeza ngokukhawuleza. Qalisa ukucoca nge-cooling okanye ukuxuba kancinci ukuze uphephe ukungalingani kwegwebu. I-catalysts zikhuthaza isantya ngaphandle kokusebenzisa, zichaphazela isantya. Ukuvuthela izinto kwenza amaqamza, amanzi aqhelekileyo enza iCO2. Ubuninzi obubekiweyo. Iminyaka kwi-Sanying ibonisa isitshixo sokunene, lungisa ixesha lokusika i-catalyst yokunyusa imveliso. Iipolyol ezingachanekanga aziphumeleli kwizicelo ezishushu. Siyila le khemikhali ukuze senze izinto ze-elektroniki.

Sibone ukuthi i-SANYING polyols ne-isocyanates zihlanganisa njani ukwenza izinto ezinkulu! Ngokufanana nokuhlanganisa iziqhelo ezimbili ezingcono ukwenza into enobunzima.

I-Polyol ne-Isocyanate zihlanganisa

Khetha iziqhelo ezimbili. Okuqala kukho i-polyol, indlela yokuqonda eneemvume zokugcina ezisemthwakathini zokugcina. Okwesibili kukho i-isocyanate, neemvume zokugcina ezinkulu zokufanana ngokupheleleyo.

Kodwa xa kuhlanganiswa i-SANYING polyol ne-isocyanate, izimvume zokugcina zifumana kusinye. Ngokufanana nokubhala isandla! I-polyol yomvume wokugcina uyagcina i-isocyanate yezimvume ezinkulu, ukwenza ubungqina obukhulu. Xa kuzekwa amaqhelo amaningi, ukuhlanganiswa kuchitha kwiqhebe lokhu kuyakha umkhosi okanye i-foam ngokwesixhobo. Le nto yokugcina iyichazwa njengokuzenzela ukuzenzela. Kukhona izikhumba ezinobunzima, izikhumba ezinobunzima, nokuhlula komkhosi omncane. Ukufanana kwazo kwenza i-polyurethane ibe yinto enobunzima nobunzima. I-SANYING iqinisekisa ukuthi zihlanganisa ngokupheleleyo njengalokho.

Kutheni kuzenzeka ukuzenzela okuhle kwe-polyol-ne-isocyanate

Xa i-SANYING polyol kunye no-isocyanate kuhlanganiswa ngokupheleleyo, izinto eziyinhle ziyakha. Okokuqala kukhona ukuthi kuzizwa kakhulu, isinyathelo sokusebenza. Emva koko kuchitha, ngokufanana nokuchitha kwe-batter.

Njengoba kuzoqonda, kwenza isikhumba. Kuma-foam, izibhubesi ziyaphakama ngokufanana nokuphakama kwe-cake! Kuma-coat, kuyabhekile.

Kuphela kwezinye zokugqibela ezinamandla, yenza umsebenzi: ukusetyenziswa kusuka kumkhiyuzo, ukukhuseleka, ukugcina ubushushu. Ukuthi kubinde kakhulu kuyinto ephambanisa ngokupheleleyo ukusetyenziswa kwayo. Umkhosi waseSANYING uyavumela ukusebenza ngokupheleleyo. Uyabonakala ngokuthemba.

Sulawula iintloko zokuphatha i-Polyol-Isocyanate zokufunyanwa ngabantu abathengayo

Ngamanye amaxesha ngezinto zaseSANYING, azikho ngokupheleleyo. Abathengi kufuneka bazi iintloko ukuze bafumane iinkcukacha. Ukusebenza kuncinane xa kubanda okanye xa kubekho inkcazelo engeyona, kwenza ukuba kubangelwe. Sulawula ngokuchitha, ujonge iinkcazelo.

Ukukhanya kakhulu kwenza ukuba kubaluleke kancinane, kwenza iibhobhobho ezingapheliyo, kusuka kwezinto eziphaya okanye kwezinto eziphaya kakhulu. Chitha ukuba kubanda, uhlwampise ukudibanisa.

Iilumpu nezinto eziphambili xa akasetyenziswanga ngokupheleleyo okanye akachitshelwanga ngokupheleleyo. SANYING ichitshela kodwa ukudibanisa kuyinto esebenzayo. Iindlela zokusebenza ezinamandla. Jonga iindikimba. Ngoko ke uzofumana iimpikiswano ezipheleleyo.
