I-polyol ne-isocyanate zizinto ezimbili eziphambili zokwenza i-foam. Zihlanganisa ukwenza imithombo eyinkimbinkimbi esibonwa kumazinto amaninzi okuzilwana. I-polyol, yindlela yemithombo yomshini, iyaphinda ngokuphinda kwe-isocyanate, oko kukho umthombo ongahleli ukuba awusetyenziswanga ngendlela efanelekileyo. Xa zihlanganisa, ziyenza i-foam engaqondi noma engaqhele, kusukela kwendlela yokusebenzisa. Le foam ichazwa kumathuthu, amasitayela weemoto, nokufaka kwemithombo. Ukujonga indlela okuyi-polyol ne-isocyanate ziyiphinda ngayo kusiza ukwazi ukusuka kumkhondo ne-structure yefoam, oko kubalulekile kumkhondo wakho nokusebenzisa kumazinto amaninzi.

Kuphi Kufuneka Uthole i-High-Density Foam ene-polyol ne-isocyanate

Kodwa ukuba uyafuna i-high-density foam, u-SANYING uyisibalo esihle sokugqiba. Baya kubona izinto ezininzi zefoam zokusebenza ngokuphinda kwe-polyol ne isocyanate (MDI) ukwenza izinto ezikhazimisekileyo, eziphambili. I-foam ene-densiti enkulu iyasebenza kumanye imithombo, njengokusebenzisa kwezinto zokuzinza apho kufuneka kunezinkumbulo ezikhazimisekileyo. Kusetyenziswa nakwakho ukubulawa kwizakhiwo zomkhosi. Ungafumana i-foam yase-SANYING emaphakamini apho abasemthwala bayaqenza izinto zabo. Okanye ungene ngqo kubo ukufumana i-foam eyenziwe ngokupheleleyo eya kufanele kuzo. I-foam ene-densiti enkulu ayikho kuphela isikhazimiso, kodwa inika nokuthandana nakho. Khetha isofa okanye isikhumba nayo, sivumela ubuhlobo bomzimba, ngoko ke abantu bayakhetha kwiindawo zabo. Ngapandle koko, iphambili, ngoko ke yindlela enobuchule yokuthenga. Nge-SANYING, uyavuma ukuthi i-foam yabo yeziqhamo esebenzisa ngokuphambili. Izinto zabo ziyasebenzisa kumanye imithombo, ziyisibonelo sokusebenzisa ngokwenzekileyo.

Ukuthi i-Polyol ne-Isocyanate ziyathatha njani ubuhlobo be-foam

Umbono wembono wemfumbi uyaphila kakhulu ngokuthi ipolyol ne-isocyanate zihambanisa njani. Xa zihambaniswe, zihlakisa ukuzalisa izibhobho, zinika umfanekiso wemfumbi ophakathi. Inani le-polyol ne-isocyanate libuyela ubude bokuphakama. Umzekelo, ukudala kakhulu kwe-polyol kusenza imfumbi ifanele, ngelishwa ukudala kakhulu kwe-isocyanate kusenza yena ibe yinkulu. Lokhu kubalulekile kumsebenzi wakhe wokusebenza kwinqanaba lomhlaba. Imfumbi efanele iyasebenza kakhulu ekukhanyeni, kodwa eyinkulu kuyasebenza kakhulu ekugciniseni amanzi noma ekugciniseni isithunzi. Ukulandelela phakathi kwezinto zombili zizigqibeleleyo. Ukuba kukhona kakhulu kweyinye kwaye akukho kweyinye, imfumbi ibe yinkulu noma ithwala kakhulu. Lokhu kubuyela ubude bokuphila kwayo nokusebenza kwayo. i-SANYING iyazi le mifanekiso, ngoko ke izinto zabo ziyasebenza kwiimfuno ezikhulu. Imfumbi yabo yadalelwa ukuze ibe yinxalenye yokuqiniseka kwayo kwaye ibe yinkulu, ibe yinxalenye yokuqiniseka kwayo phakathi kwezinqanaba zokuphakama. Ngaphezu koko, indlela okufuneka kuyenzeka kuyo imfumbi kusenza kumbono wakhe. Ngezici zika-SANYING, unokwazi ukuba izixhumanisi zabo zisiza kumsebenzi kwaye zibe yinxalenye yokuqiniseka kwayo kwiimfuno zokusebenza.

Ukukhetha i-Polyol ne-Isocyanate eNgeyona Kulo Kukwenza i-Mfumbi

Xa uyakwenza imfumbi, khetha engeyona polyol kunye no-isocyanate kubalulekile kakhulu. Lezi zinto zikusiza ukwakha isithuthi sokufomela nokuthambo. Ukuthambo kukuthi yintoni inkulu ngokwezinye zokukhula. Uma ufuna ifomela engeyona nje kwaye engeyona nje, khetha uhlobo lwepolyol kunye ne-isocyanate esifanelekileyo. I-polyols ziyinkqubo zokwakha ifomela. Zibonakala ngamathuba amaninzi, ziyakwenza ifomela ibe engeyona nje okanye ibe enkulu. Ukufumana umthwalo ongeyona nje, khetha i-polyol engeyona nje. Ukufumana umthwalo ongaphambili, khetha i-polyol enkulu. I-isocyanates zisebenza ngokunye ne-polyols ukwakha into enkulu. Uhlobo lwe-isocyanate luyakuthatha ukuthambo futhi. U-SANYING unenqaku lezinto zombini, ngoko ke kufuneka ukufumana umxholo wokusebenza ngokulinganayo. Khumbula, ukufumana ukuthambo okufanayo, qhathanisa izihlobo ngokucacileyo. Ukuxhuma izihlobo ezahlukeneyo kuzakuthatha iziphumo, ngoko ke zizame kwanasekuqala ngaphambi kokwenza inkqubo enkulu.

Umgama we-Isocyanate kwi-Polyol kunye ne-Thambo le-Fomela

Umgama we-isocyanate kwi-polyol uyisiseko, ngoba uyaphatha indawo ngqo. Ukuba kukhulu kakhulu ukwenzela isocyanate, i-foam ibecala kakhulu kwaye ibe khulu kakhulu. Lokho kuyakubangela ukungafanele kwi-foam yezicatshulwa okanye izihlalo. Kodwa ukuba akukho isocyanate esifanayo, i-foam ibe mncane kakhulu kwaye ayikwazi ukugcina umdlalo walo. Umgama otekhile uyisiseko. Kwi-foam yezinto zokusebenza, sifuna ukuba ibe khulu kakhulu, ngoko ke umgama omkhulu kwi-isocyanate kwi-polyol. Isiqhelo se-SANYING sibonisa umgama otekhile kwiimfundo. Imisebenzi eyahlukahlukene iyadinga imigama eyahlukahlukene, njengoko kufuneka kwi-foam yokuvala kwaye kwi-foam yezixhobo. Ukuzivocavoca kuyisiseko. Yenza amaqhezu amancinane kuqala ukuze ubone indlela okuqhelekileyo kuyaphatha indawo. Ngale ndlela, unyuse phambi kokuphanda kakhulu. Ukuzazi indlela okuqhelekileyo kuyaphatha indawo kusiza ukwenza i-foam enobunzima obuhle kumazinto ongafuni.

Abathengisi bokuthengiselwa kufuneka bazi ntoni mayelana ne-density ye-polyol ne-isocyanate

Abamkhubuzi base-Wholesale kufuneka bazi ukuba i-polyol kunye nezinto zokubhala kwe-isocyanate ziyaphakamisa izinto. Xa usebenza ngokuphatha i-foam, i-density iyaphakamisa ubukhulu nobukhulu. I-density ephakamileyo iphakamisa isikhathi eside, iphakamisa ukuthuthukisa, ngoko ke i-low density ibalulekile kodwa ayikho nokuthuthukisa. U-SANYING uphawula amaxwebhu ase-polyols kunye nezinto zokubhala kwe-isocyanates, ukuze usondele kwezindlela zokuziphatha. Funa ukuzibona ngezinye izinto zokusebenza. I-foam yemattress inefuna ukubaluleka nokuthuthukisa, ngoko ke i-packaging inefuna ukuba ibe entle kodwa ingenakho. Ukuziqonda i-density kusiza ukuthola i-foam eyodwa. U-SANYING unakho ukuthola i-density eyodwa, ngoko ke qiniseka ukuthi uyafuna ntoni. Lokho kukhona kumangaliso kubamkhubuzi abanamathuba ahlukahlukene. Ngokugcwele, wazi ukuba umgweba wokuphola polyol a ne-isocyanate ziyaphakamisa i-density kuyimfanele ukuziphatha ngokuchanekileyo ekuphatheni i-foam. Ngale ndlela, uqinisekisa ukuthi i-foam eyodwa iyasebenza ngokuchanekileyo.
