Polyester resin: izakhiwo kanye isicelo, izici

Resin polyester has a ububanzi impela kwesicelo. Le mikhiqizo etholakala ngokuzikhandla ukukhiqizwa chemical ngenqubo ethile eziyinkimbinkimbi yokuxuba futhi ngokucubungula izinto. Ukwakheka polyester resin kukhona alcohols, bona akhiwa ngenxa yokucwenga mepropriyaty. Olunye ulwazi mayelana polyester inhlaka lapha.

Lokhu glycols (isib monoethylene glycol, diethylene, triethylene, propylene, butylene), kanye glycerol, pentaerythritol, xylitol. Acid: orthophthalic acid, adipic acid, sebacic acid, terephthalic acid, anhydride maleic, kuhlanganise methacrylic futhi acrylic acid. Uma kudingekile, ukuguqulwa polyester inhlaka izicelo yemifino amafutha kanye amafutha, kanye resin acid.

With ukusetshenziswa mikhiqizo ukukhiqiza imikhiqizo ehlukahlukene. Lokhu sikebhe for izikebhe, kanye eziningi imininingwane ngabo, kungcono zangasese, surfboards, njll

Ukusebenzisa kwakhe lezi zakhi etholwe emikhakheni ehlukahlukene yokukhiqiza, ekukhiqizeni imikhiqizo amelana amakhemikhali. Babonisa ngokucacile ngokwabo emsebenzini wokukhiqiza izivakashi kanye yezemidlalo, kanye ukudalwa amapayipi izesekeli, isibonelo, abantu abaningi baye bezwa nomqondo ubhavu acrylic noma acrylic eshaweni ugqoko, njll

Polyester inhlaka babe kakhulu izinga izici. Ukuze labo zihlanganisa:

• ukumelana noma yiziphi izinguquko ku lokushisa (lokushisa luyehluka in the ububanzi 60 - 100 degrees);
• eyingqayizivele okusezingeni eliphezulu ukumelana mechanical (ngemva solidification ephelele has amandla amakhulu kanye ubulukhuni ezingeni);
• ukumelana izinto of amakhemikhali ukwakheka (ngaphandle zezimboni);
• ukugqoka ukumelana naso futhi kwenze inkonzo eside ekuphileni imikhiqizo kusuka polyester inhlaka original izinga izici ngokuphelele hhayi encishisiwe;
• imikhiqizo ukwaziswa okufanayo cishe ukuqeda ukuncipha.

Ukusebenza nge impahla ezifana polyester resin, ke akakubangeli eyinkimbinkimbi futhi kudinga efaneleyo kancane nesipiliyoni. Into esemqoka - ukuze bagcine eziyisisekelo imithetho yokuphepha wokusebenzisa leli ukwakheka kanye acabangele umehluko wemisindo nemiqondo yamagama athile. Ngokwesibonelo, resin phakathi kwenqubo eqandisiwe futhi umkhiqizo wokugcina waba sezindawo ngenhla echazwe wamandla nokwethenjelwa, kubalulekile ukusebenzisa hardeners ekhethekile.

Phawula futhi ukuthi ngemva ukuxuba resin kanye hardener kufanele asebenze ngokushesha ukuze nqubo yaqala ukusabela exothermic. Ngemuva kokufaka isicelo ezidingekayo ukuba iyinike isikhathi kakhulu yokuzigxilisa futhi uthathe ukuma oyifunayo.

Uma unesithakazelo ukuthenga lo mkhiqizo, kudingeka sisithathe ngokungathi sína lesi ukukhetha kwezimboni ezihlinzeka ngempahla. Kufanele ihlinzeke zonke izitifiketi ezidingekayo ukuze imikhiqizo yabo. Khona-ke uyoba ukuqinisekiswa kukhwalithi ephezulu. Phela, izinga kubalulekile kithi. A kuya imikhiqizo efana polyester resin bayanda izidingo. Yingakho kudingeka embuzweni sina ukuthenga kwabo.
