I-polyether polyol iyi-chemical material eluhlaza ebaluleke kakhulu, esetshenziswa kabanzi ekukhiqizeni izimboni njengokuphrinta nokudaya, ukwenza amaphepha, isikhumba sokwenziwa, izindwangu, izindwangu, amapulasitiki egwebu kanye nokuthuthukiswa kwe-petroleum.Ukusetshenziswa okukhulu kwe-polyether polyol ukukhiqiza i-polyurethane (PU) igwebu, kanti i-polyurethane isetshenziswa kakhulu ezintweni zangaphakathi zefenisha, izinto zikagesi, ezokwakha, izinto zezicathulo, izinto zikagesi zasendlini, izimoto kanye nokupakisha.Imboni yokuhlobisa ibusa sonke isidingo semakethe, ilandelwa imboni yezokwakha, kuyilapho imakethe yezinto zikagesi zasendlini kanye nemboni yezitimela ezihamba ngesivinini esikhulu kuzoba izigxobo ezibaluleke kakhulu zokukhula kwesidingo se-polyurethane esizayo.

1. Okokuhlanza noma okokuhlanza umoya

I-L61, L64, F68 isetshenziselwa ukwenza izinto zokwenziwa zokwenziwa ezinegwebu eliphansi kanye nokuhlanza okuphezulu;

I-L61, L81 isetshenziswa njenge-defoamer embonini yokwenza iphepha noma yokuvutshelwa;

I-F68 isetshenziswa njenge-defoamer ekujikelezeni kwegazi emishinini yokwenziwa yamaphaphu enhliziyo ukuze kuvinjwe umoya ukuthi ungangeni.

2. Izisetshenziswa kanye nama-emulsifiers

Ama-polyethers anobuthi obuphansi futhi avame ukusetshenziswa njengezihlanganisi zemithi nama-emulsifiers;zivame ukusetshenziswa ngomlomo, izifutho zamakhala, iso, amaconsi ezindlebeni kanye nama-shampoos.

3. I-ejenti yokumanzisa

Ama-polyethers angama-agent asebenzayo okumanzisa futhi angasetshenziswa ekugezeni kwe-asidi ukudaya izindwangu, ukuthuthukiswa kwezithombe kanye ne-electroplating, kusetshenziswa i-F68 ezigayweni zikashukela, ushukela omningi ungatholakala ngenxa yokwanda kwamanzi.

4. I-ejenti ye-Antistatic

Ama-polyether ama-antistatic agents awusizo, futhi i-L44 inganikeza ukuvikelwa okuhlala isikhathi eside kwe-electrostatic kumafayibha okwenziwa.

5. Umhlakaza

Ama-polyethers asetshenziswa njengama-disperants embotsheni ye-emulsion.I-F68 isetshenziswa njenge-emulsifier ku-vinyl acetate emulsion polymerization.I-L62 kanye ne-L64 zingasetshenziswa njengezifaki-zibulala-zinambuzane, izipholile kanye nezinto zokugcoba ekusikeni nasekugayeni insimbi.Isetshenziswa njenge-lubricant ngesikhathi se-vulcanization yerabha.

6. I-Demulsifier

I-polyether ingasetshenziswa njenge-demulsifier kawoyela ongahluziwe, i-L64 ne-F68 ingavimbela ngempumelelo ukwakheka kwesikali esiqinile emapayipini kawoyela, futhi ingasetshenziselwa ukubuyisela uwoyela wesibili.

7. Izinsiza zokwenza amaphepha

I-polyether ingasetshenziswa njengosizo lokwenza iphepha, i-F68 ingathuthukisa ngempumelelo ikhwalithi yephepha eliboshwe;ibuye isetshenziswe njengensiza yokugeza.

8. Ukulungiselela nokusebenzisa

Imikhiqizo yochungechunge lwe-polyether polyol isetshenziselwa ikakhulukazi ukulungiswa kwegwebu le-polyurethane eliqinile, elisetshenziswa kakhulu eziqandisini, iziqandisi, izimoto eziqandisiwe, amaphaneli okushisa ukushisa, ukufakwa kwamapayipi neminye imikhakha.Umkhiqizo olungisiwe une-conductivity ephansi yokushisa kanye nokuzinza okuhle kwe-dimensional, futhi ubuye ube yinto ebalulekile yokusetshenziswa kokulungiselela i-polyether ehlangene.Ukukhiqizwa kwe-polyether polyols

Embonini ye-polyurethane, isetshenziselwa ikakhulukazi i-polyurethane foam, futhi izinhlobo eziyinhloko i-polyoxypropylene polyol ne-polytetrahydrofuran ether polyol.

I-vinyl polymer exhunyelelwe i-polyether polyol ijwayele ukwaziwa ngokuthi "i-polymer polyol" (i-PolyetherPolyol), efushanisiwe njenge-POP.I-polymer polyol isekelwe ku-polyether polyol evamile (ngokuvamile i-polyether triol ethambile ye-foam, i-polyether ephezulu yokusebenza), ingeza i-acrylonitrile, i-styrene, i-methyl methacrylate, i-vinyl acetate, i-chlorine Ethylene namanye ama-vinyl monomers kanye nama-initiators akhiwa nge-radical graft polymerization cishe ngamadigri ayi-100. futhi ngaphansi kokuvikelwa kwe-nitrogen.I-POP iyi-polyether polyol egcwele i-organically esetshenziselwa ukulungiswa kwezinto ezinomthwalo ophezulu noma imikhiqizo ye-polyurethane ephezulu eguquguqukayo kanye ne-semi-rigid polyurethane foam.Ingxenye noma yonke le polyether egcwele i-organically isetshenziswa esikhundleni se-polyether polyether-purpose polyols, engakhiqiza amagwebu ane-low density kanye nokusebenza okuphezulu okuthwala umthwalo, okungagcini nje ukuhlangabezana nezidingo zokuqina, kodwa futhi kusindisa izinto zokusetshenziswa.Ukubukeka ngokuvamile kumhlophe noma kuphuzi olubisi olukhanyayo, owaziwa nangokuthi i-polyether emhlophe.

Isimemezelo: Isihloko sicashunwe ku-Lunan Polyurethane New Material ku-WeChat 10/2021 Kuphela ukuxhumana nokufunda, ungenzi ezinye izinjongo zezohwebo, akumeleli imibono nemibono yenkampani, uma udinga ukuphrinta kabusha, sicela uthinte umbhali wokuqala, uma kukhona ukwephulwa komthetho, sicela usithinte ngokushesha ukuze wenze ukususa ukucubungula.
