PET mtundu masterbatch

Dzina lonse la masterbatch la mtundu limatchedwanso mtundu, ndi mtundu watsopano wa polima wamtundu wapadera, umapangidwa ndi utoto kapena utoto, zonyamulira ndi zowonjezera za zinthu zitatu zofunika, ndiye mtundu wapamwamba kwambiri kapena utoto womwe umalumikizidwa ndi utomoni ndi utoto. analandira akaphatikiza, tingaone ngati pigment maganizo, kotero mitundu mphamvu ndi apamwamba kuposa pigment palokha.Masterbatches amagwiritsidwa ntchito makamaka papulasitiki.Kuti mukwaniritse mtundu womwe mukufuna muzinthu zapulasitiki kapena mphira.

Njira yaukadaulo:

Zofunikira za kupanga masterbatch ndizovuta kwambiri, nthawi zambiri zimagwiritsa ntchito njira yonyowa.Mtundu wa masterbatch umapangidwa ndi kugaya gawo lamadzi, kusintha kwa gawo, kutsuka, kuyanika ndi granulation, mwanjira iyi yokhayo yomwe imatha kutsimikiziridwa kuti mtundu wa mankhwalawo ukhale wabwino.Komanso, pamene pigment akupera, mndandanda wa mayesero ayeneranso kuchitidwa, monga kuyeza fineness wa mchenga akupera slurry, kuyeza kufalikira katundu mchenga akupera slurry, kuyeza olimba zili mchenga akupera slurry ndi kuyeza ubwino wa phala lamtundu.

Ubwino wa masterbatch:

1. Pangani pigment kukhala kubalalikana bwino mu mankhwala

Popanga mtundu wa masterbatch, pigment iyenera kuyengedwa kuti ipititse patsogolo kubalalitsidwa ndi mphamvu ya utoto wa pigment.The chonyamulira chapadera mtundu masterbatch ndi chimodzimodzi ndi pulasitiki zosiyanasiyana mankhwala, ndipo ali yofananira bwino, ndi pigment particles akhoza bwino omwazikana mu mankhwala pulasitiki pambuyo Kutentha ndi kusungunuka.

2. Ndizopindulitsa kusunga kukhazikika kwa mankhwala a pigment

Ngati pigment ikugwiritsidwa ntchito mwachindunji, chifukwa cha kukhudzana kwachindunji kwa pigment ndi mpweya panthawi yosungira ndikugwiritsa ntchito, pigment idzayamwa madzi, okosijeni ndi zochitika zina, ndipo mtunduwo utatha kupangidwa, ubwino wa pigment ukhoza kusinthidwa. nthawi yayitali chifukwa chonyamulira utomoni chidzalekanitsa pigment kuchokera mumlengalenga ndi madzi.

3. Onetsetsani kukhazikika kwa mtundu wa mankhwala

Tinthu tating'onoting'ono tomwe timafanana ndi tinthu tating'onoting'ono, tomwe ndi yosavuta komanso yolondola pakuyezera, sikumamatira ku chidebe posakaniza, ndipo kusakanikirana ndi utomoni kumakhalanso kofananira, kotero kutha kutsimikizira kukhazikika kwa kuchuluka kwake. , kuti atsimikizire kukhazikika kwa mtundu wa mankhwala.

4. Tetezani thanzi la wogwiritsa ntchito

Pigment nthawi zambiri imakhala ya ufa, yosavuta kuwuluka ikawonjezeredwa ndi kusakanizidwa, ndipo imakhudza thanzi la wogwiritsa ntchito pambuyo pokokedwa ndi thupi la munthu.

5. Sungani chilengedwe chaukhondo komanso chopanda banga.

6. Njira yosavuta, yosavuta kusintha mtundu, kusunga nthawi ndi zipangizo.
