Ngokwesikhathu ndifumanekile izicateleni zomshayeli eziningi eziqoqweni kulo mhlaba ongenzi ukuthiwelelwa ngazo ngezinye izigxile zokusebenza ezikuxhasa kuhlukeleka esiphakamisini. Ngokwesibho, amagama apha akuyizinto elizenzeka yonke leli lokuhlula kwiingxenye yokusebenza, lesi siyisebenzela nokuba ndim ndinguwe. Zingaphi iindlela zezi zinto?
Ngendawo, ipoliyurithane ingene ukuthiyo lokungakhululekiswa kunye nezi zinto ezinomsindo, futhi lezi zinto zihlanganisa umthetho wokuqala wesintshontsho.
Yeyiphi yezinye izinto ezinikezela kulesi sikhathi sokukhululekiswa kokusebenza, okanye lowo olunye uvela nokuba olunye lavela, kwaye lavela kufanele ukubonakale kusasa kumthetho wokuphakamisa, lokhu kulula ukuthiyo lokuncedisiweyo nokuba kungcono, lokhu kungukholo lwesintshontsho.
Uma kubangako, phakathi sisebenzisa ukubona ngaphandle kokuthi le nto ifumanekileyo; uma kungaba into enemva kwezikhono zethu, phakathi sisebenzisa ukubona ukuba singayazi ukuba kunye neentsha ezizenzekelayo ziyavakashwa ngokwesikhono.
Ngokushesha: siyazi wonke umoya waseShanghai Gaoqiao ngu-2000 kunye noJinpu eKhenjini ngu-1070. Ngokumisa, amandla okuhlukene kwezi zintathu ezidingekayo emasimini apho abe slow-rebound polyether kuzo kanye nokulandelana nge-240. Kxaso, kwindawo yokugcina lokwenza, amandla amahluko angamashumi amabili amatatu angenziwayo kuhluke.
Emva kwaloo moya wesikhashana, bazo babenziwe ngokubanzi njengobunye obungaba ngendlela yakho, kunye nokuba ayinakuyisingeniswa ngaphandle kokufuneka kuzo kusetyenziswa ngokuphephandwayo.
Ngokushesha, ukugcina lwe slow-rebound polyether lokusebenziswayo kwesitsha isebenza ngokwesentla sokucacisa ngokuthi kulula ukuba kunezinto ezininzi ezifumanekileyo, futhi kungenziwayo ukuba zihlukanise izilungiselelo ezinikezayo kwiimbhokisi yokuqala yawo.
Ngokugcina, igumbi elileyo ligama lakhe lokulayishwa, ulwandle oluninzi olungaphezulu luhlukwe kakhulu kunye nequkuqethu.
Inani lelwandle oluninzi olungaphezulu kulayishwa kwiqhophiso lapho ilayishwa iphuzu lenkululeko kukho okuningi, kunye nokulayishwa kwesi-nye silikon (isithuthi) yayingasekubeni ngeesi-nye silikon (isithuthi). Ngakwesobizo, ukuba use uhlala ngaphandle komoya okanye ihlukwe, yinto yokulayishwa yokuhlukwa kokuphucula kuhlanganiswa okuningi, kunye nokulayishwa kwesi-nye silikon uzokubonakala kusihlangene.
Ngaba nguyiphi indlela yokudinga inani lesi-nye sokuhlukwa nokulayishwa kwesi-nye silikon?
Kwiqhawu lwe-polyurethane, ngokusho kwezikhundla zasemva kwe-slow rebound sponges kunye nezi sponge ezinye, njengamaxesha amahhala okunquma kakhulu, futhi wonke umsebenzi wabo, iindlela zakubhala zakho zazibonakale ngaphandle kokuba zizidinga noma zizama ukuwona. Ngoko ke, islow rebound sponge ihlukile kakhulu ngenxa yokuba ukudibanisa kwake kube ngaphambili ukuba uzame ukusetyenziswa komsebenzi wokuhlola nokulula, kodwa ngaphezulu lokuncedisiyo lwesicwangciso.
Wonke umsebenzi wenza, xa uthanda imigomo yakhe, ungavikela ukusebenza. Wonke umsebenzi wakho weslow rebound sponge, xa usetyenziswa, ngokuba isponge singayithola indlela yokuphumelela phakathi kwezinhloko zomphilo, izibophelele zingabe zibuyele ekubeni lokungabuyiseli, noma zibe zincedise phakathi kwezintlonkana zezinto eziphathelayo. Lokhu kuxoxa ukuba kunezinto ezimbini: yililo yesilikon yiyingca eyenziwayo, kufuneka leliyiwe ngokwesilinganiso.
Yeyokuqala, ukuba umkhuhlane wokuvula kweesponji kufuneka akukho imiphumela yezithomatha, ngalesi sizini sikhona okubalulekileyo lokuhlola lokulandelayo, kunye nokususa kwakhona lokuhlola lokulandelayo kufuneka lihlale.
Umphumelelo.
Umphumelelo ungenzi ukuthi ipolimeri yesethenjisi lapho, futhi ngokwesikhatsi esisodwa sihlanganise ukulinganisa emva kokuthi.
Kunezinye ezimbili zityalo zokuthi zingaba umphumelelo: amayisithree amayinene neemphumelelo yenyanya, njengokusho triethylenediamine, pentamethyldiethylenetriamine, methylimidazole, Amur1, ngeza. Stannous octanoate, dibutyltin dilaurate, potassium acetate, potassium octanoate kunye noorganic bismuth ifanele yiimphumelelo yenyanya.
Ngoku sive ezi zityalo zonke zeemphumelelo ezilandelwe, ezintathuwayo, ezinkompound kunye neemphumelelo ezidingekayo VOC, zonke izinto zakho zihlala emva kokuthi.
Ngokusho, i-smury series yamagama olandelayo eGas products Company, ingxenye yobunxele yokugcina yona yikusho triethylenediamine:
L s-y33LV inekileyo 33% triethylene diamine / 67% dipropanediol.
L smury R8020 triethylene diamine inhlawula 20% DMEA 80% DMEA.
L smury S25 triethylene diamine inhlawula 25% / butanediol 75%.
L s-y8154 triethylenediamine / acid delayed catalyst.
L Smury EG triethylene diamine inhlawula 33% / ethylene glycol 67%.
L Smury TMR series trimerization.
L Smury 8264 mixed block bubble and balanced catalyst.
L Smury XDM low odor catalyst.
Ngokubanzi bezincatalisi eziningi, kufuneka ushayiswe iindlela zombini zezincatalisi kunye noma zikhathale ngaphandle kokuthi ufake imbelekiso yepolyurethane, yinto engeyiyo, yebhala lokugelwa kunye nokusetyenziswa kokubheka, uphakamiso lwendalo lokugelwa kunye nokubhala lokugelwa, kunye nokuphakamiswa lokubhala lokugelwa kunye nokulushwa kwemali, kwaye okuningi.
Foam stabilizer.
Iphakathi leyiya ngokwengeza umthengi wemateriali yefoymu, ukungasibekisa ifoymu nokugcina umbhali, kungenelela umthengi wesintathu kwezinye izinhlobo, kunikeza ukufomethwa kwesintathu, kunyusa ukubaluleka kwezinsimbi zifoymu, kunikeza ukusetyenziswa kwezinsimbi ezikhulu nezingane, kunyusa ukubaluleka kwezinsimbi zifoymu, kunyusa ukusetyenziswa kwezinsimbi zifoymu, kunyusa ukusetyenziswa kwezinsimbi zifoymu, kunyusa ukusetyenziswa kwezinsimbi zifoymu.
Ngaphandle kokuba inani lefoymu stabilizer liyincinci, ulula lokulandelayo kwindawo yesithunzi esingabo, iindlela zakuphakamisana nokuhlola kwezinto.
Ngokuqondile, i-hydrolytic silicone / polyoxolefin ether block oligomers ziye kuzama kwiChina. Ngoba ziyasebenzela ngemiphahla yezifoymu ezidingeki, imigca yezililo ezinomsindo kanye nezililo ezinomsindo luchasene, kungenelela ukusetyenziswa kwezililo ezindala ezifanayo ngezililo ezinomsindo. I-silicon stabilizers zizivumelekileyo ezifoymu.
Ngoko ke, kwiqhagamshelo kwesixhobo somphumela wezilungiselelo, kufuneka sithetha ngaphakathi iphumo yakhe kunye nokugcina, ushobiswa, ashiyiswayo, ukuba akudibane ngokulandelayo imisebenzi esincinci.
Ngokuvamile, isilungiselelo sesiqiniseko esilandelayo silinganiso singayaziwe kwindawo yokuphucula esizenzekelayo, ngoko ke izixhobo zizoba zihamba, ukuze ziphumeleye umphumela, isilungiselelo sezilungiselelo esizenzekelayo singayaziwe kwindawo yokuphucula esilandelayo, ngoko ke izixhobo zizoba zihamba, ukuze ziphumeleye umphumela.
Ngokuthi kufuneka ukusetyenziswa kwezinto ezifana nezindawo zokuhlola iimvubo, iindlela zakuzalwa nokubheka zikhetha amaxwebhu okanye amaxwebhu apha eziqinisekayo nokukholelwa kokuthi abantu babuyekeze amaxwebhu okanye amaxwebhu apha eziqinisekayo, ngoko ke iindlela zazalwa nokubheka zikhetha amaxwebhu okanye amaxwebhu apha eziqinisekayo, njengokuba ngeSmury DC6070, yintlango yokuhlola i-TDI, kunye noSmury DC2525, yintlango yokuhlola i-MDI.
