Polyurethane Hot Melt Adhesive (PUR): Zvakawanda Sei Unoziva

Polyurethane Reactiveaka PUR,Chikamu chikuru kuguma-isocyanate polyurethane prepolymer, ine simba rakanakisa rekunamira uye kuchinjika, mukuwedzera kune yakanakisa tembiricha, kusamira kwemamiriro ekunze, kusapfeka kusaga, kusaita ngura uye kuramba kuchembera, uye yakashandiswa zvakanyanya mukunamira, machira, furo, elastomers nemimwe minda.

Kuumbwa kwezvinhu zvakasvibiswa

PUR inonyanya kuumbwa ne macromolecular polyols, isocyanates, tackifying resins uye zvishoma zvekuwedzera uye mafirita.

Polyurethane Reactive(Pur) inogona kupatsanurwa muzvikamu zviviri: imwe inonzi thermoplastic polyurethane elastomer inopisa inonyunguduka inonamira, uye imwe yacho inobata polyurethane inopisa inonyungudika inonamira. Reactive polyurethane inopisa yakanyunguduka adhesive yakakamurwa kuva yakavharwa mhando uye mwando kurapa inopisa nyungudika mhando. Kune rudzi rwakavharwa, kupisa kwekuparadzanisa kwemhando yakavharwa kwakakwirira kusvika 100 ° C kana kupfuura, iyo ichaita kuti mabhubhu mumutsetse wekunamatira, saka inongoshandiswa pakugadzirisa kurapwa. Iyo hunyoro-inoporesa inopisa-yakanyunguduka polyurethane adhesive inhengo imwe chete, inonyungudutsa-isina mhando, inopindirana nemirairo yekuchengetedzwa kwezvakatipoteredza, iri nyore kushandisa, uye ine maitiro anofananidzwa neanonyungudutsa-based-reactive types.

Pur glue ine mabhenefiti ekukurumidza kubatanidza kukurumidza, kwete-chepfu, yakapusa yekubatanidza maitiro, uye yakanaka yekubatanidza simba uye kuchinjika. Nokudaro, yakashandiswa zvakanyanya mukusunga mabhuku, kuiswa chisimbiso, kugadzira shangu, machira, nezvimwewo. Uye mumakore achangopfuura, kwave kune zvitsva zvitsva maererano nekusiyana uye kushanda.

 

Mushure mekunzwisisa uku kana iwe uchinzwisisa polyurethane inopisa inonyungudutsa adhesive, Dr.Douglas glue nyanzvi vacharamba vachivandudza iwe muPurking kuti unzwisise maitiro uye kugadzirwa kwePur glue. Isu tine ruzivo rwechiremera chePur glue muPeople's Republic of China, uye isu tichaziva nezvePur glue. ipa mhinduro.Bata nesu nhasikudzidza pamusoroyedu pur glue nyaya, uye kunzwisisa mashandisirwo epur glue kugadzirisa yakakunamira yekunamira iwe.
