M'makampani amasiku ano opanga zida zomangira, kuchuluka kwa polyurethane kumawonekera pamsika.Polyurethane ndi zinthu zosunthika, koma anthu ambiri samamvetsetsa kuti polyurethane ndi chiyani kapena zomwe amachita.Poyankha izi, mkonzi walemba izi kuti akupatseni sayansi yotchuka.“

Polyurethane ndi chiyani?

Dzina lonse la polyurethane ndi polyurethane, lomwe ndi liwu lachidule la ma macromolecular compounds okhala ndi magulu obwerezabwereza a urethane pa unyolo waukulu.Polyurethane ndi kagulu kakang'ono ka urethane m'dziko langa, ndipo imathanso kukhala ndi ether ester urea biuret urea gulu loyamba la polyurethane introduction gulu.Amapangidwa ndi polyaddition wa organic diisocyanate kapena polyisocyanate ndi dihydroxyl kapena polyhydroxyl pawiri.Zinthu za polyurethane zimakhala ndi ntchito zosiyanasiyana, zimatha m'malo mwa mphira, pulasitiki, nayiloni, ndi zina zotero, zomwe zimagwiritsidwa ntchito m'mabwalo a ndege, mahotela, zomangira, mafakitale agalimoto, migodi ya malasha, mafakitale a simenti, nyumba zapamwamba, nyumba zogona, malo, miyala yamitundu. art, park etc.

Ntchito ya polyurethane:

Polyurethane ingagwiritsidwe ntchito popanga mapulasitiki, mphira, ulusi, thovu lolimba komanso losinthasintha, zomatira ndi zokutira, etc. Ikhoza kugwiritsidwa ntchito m'madera osiyanasiyana a moyo wa anthu ndipo imakhala ndi ntchito zambiri.

1. thovu la polyurethane: logawanika kukhala thovu lolimba la polyurethane, thovu lolimba la polyurethane ndi thovu losinthika la polyurethane.Chithovu cholimba cha polyurethane chimagwiritsidwa ntchito makamaka pomanga zida zotchinjiriza, zotenthetsera zamafuta (kutchinjiriza kwa mapaipi, ndi zina), zofunikira zatsiku ndi tsiku (mabedi, sofa, ndi zina zotere, mafiriji, ma air conditioners, etc. , etc. core material. ), ndi zoyendera (zida monga ma cushion ndi siling’i za magalimoto, ndege, ndi magalimoto apanjanji).

2. Polyurethane elastomer: Polyurethane elastomer ili ndi ubwino wa mphamvu yabwino yamakokedwe, mphamvu ya misozi, kukana kukhudzidwa, kukana kwa abrasion, kukana nyengo, kukana kwa hydrolysis, kukana mafuta ndi zina zotero.Amagwiritsidwa ntchito makamaka popangira zida zokutira (monga chitetezo cha ma hose, ma washer, matayala, zodzigudubuza, magiya, mapaipi, ndi zina), zoteteza, nsapato, matayala olimba.

3. Polyurethane madzi zinthu: Polyurethane madzi zinthu ndi yabwino kwambiri ntchito.Ikhoza kusakanikirana ndi kupakidwa pamalopo ndikuchiritsidwa ndi kutentha kwabwino ndi chinyezi, ndi wosanjikiza madzi opanda seams, elasticity mphira ndi ntchito zabwino angapezeke.Ndipo zosavuta kukonza pambuyo kuwonongeka.Nthawi zambiri amagwiritsidwa ntchito ngati zida zomangira, njanji ndi zida zam'munda, njanji zothamanga, zida zapansi papaki, mafelemu azenera otenthetsera, etc.

4. Kuphimba kwa polyurethane: Kupaka kwa polyurethane kumakhala ndi zomatira zolimba, ndipo filimu yophimba imakhala ndi kukana kwabwino kwambiri, kukana madzi ndi kukana mankhwala.Amagwiritsidwa ntchito makamaka pakuyala mipando, zokutira zomangira ndi inki zosindikizira zamakampani.

5. Zomatira za polyurethane: Kuchita kwa mankhwala ochiritsidwa kungasinthidwe mwa kusintha chiŵerengero cha isocyanate ndi polyol, kuti athe kukwaniritsa kumatira kwakukulu ku gawo lapansi, kukana madzi abwino, kukana mafuta ndi kukana mankhwala.Zomatira za polyurethane zimagwiritsidwa ntchito kwambiri pakuyika, kumanga, matabwa, magalimoto, kupanga nsapato ndi mafakitale ena.

6. Zida Zachilengedwe: Polyurethane ili ndi biocompatibility yabwino kwambiri, motero imagwiritsidwa ntchito pang'onopang'ono ngati zida zamankhwala.Itha kugwiritsidwa ntchito popanga ma pacemakers opangira mtima, mitsempha yamagazi yokumba, mafupa opangira, am'mero ​​ochita kupanga, impso zopanga, nembanemba zopangira dialysis, etc.

Zomwe zili pamwambazi ndi zina zokhudzana ndi zomwe zili ndi polyurethane ndi ntchito ya polyurethane yomwe mkonzi wakukonzerani.Polyurethane pang'onopang'ono ikuyamba kukhazikika pamsika wa zida zomangira chifukwa cha kukana kwake komanso mawonekedwe ena.Ma Netizens amatha kugula malinga ndi zosowa zawo zapakhomo.

Chidziwitso: Nkhaniyi idatengedwa kuchokera ku https://mp.weixin.qq.com/s/c2Jtpr5fwfXHXJTUvOpxCg(ulalo walumikizidwa).Pokhapokha kuyankhulana ndi kuphunzira, osachita zina zamalonda, sikuyimira maganizo ndi malingaliro a kampani, ngati mukufuna kusindikizanso, chonde funsani wolembayo woyambirira, ngati pali kuphwanya, chonde tilankhule nafe nthawi yomweyo kuti tichite kukonza.
