Mphira osakaniza pa gumming Miyala

Gumming ndi imodzi mwa njira zipangizo dzimbiri chitetezo. Gumming - kugwiritsa ❖ kuyanika mphira pa pamalo poyera mu utumiki kwa malo aukali (zidulo, alkalis, mpweya).

The jombo mankhwala ntchito gumming ndi umagwiritsidwa pamwamba zitsulo, ndi limene limalumikizana pa vulcanization. Pokhapokha ntchito apamwamba mphira kusakaniza.

Gumming - njira chitetezo dzimbiri kwa kali zitsulo cha ofalitsa zikuwononga monga organic zidulo, soda, mchere njira. Njira angapo ubwino pa njira zina chitetezo dzimbiri, ndicho, ❖ kuyanika:

- ali mkulu madzi kukana ndi kukana mankhwala;

- kukana kuti kumva kuwawa;

- kukana kuti yofanana zazikulu katundu;

- kukana kusinthasintha kwambiri kutentha;

- lili ndi mpweya permeability otsika.

Ndi gumming kukwaniritsa kuwonjezeka avale kukana ndi kutentha kukana zitsulo. Njira amateteza zitsulo pamalo mankhwala osiyanasiyana, kuphatikizapo mikondo, ntchito m'mafakitale zosiyanasiyana. chitetezo ngati akhoza kwambiri kuonjezera moyo utumiki wa migodi ya. Tikumbukenso kuti pambuyo processing amapeza mankhwala ndi katundu dielectric. Zinthu nthawi zambiri zosiyanasiyana gumming thanki ndi akasinja kwa yosungirako ndi mayendedwe zidulo, alkalis ndi zinthu zina zomwe zikuwononga.

Pamene zikugwira rubberizing ankavala zitsulo pamalo yafupika ndi ❖ kuyanika atsopano amenewa, omwe amagwiritsa yaiwisi labala, silikoni, polyurethane.

Gumming ikuchitika ndi otentha kapena ozizira chikukonzekera.

Mwa njira ya otentha rubberizing ogwiritsa (popanda kugwiritsa ntchito mawonekedwe kapena ntchito) labala chikugwirizana ndi pamwamba zitsulo pa vulcanization. Iwo amagwiritsa silikoni mphira wa mkulu khalidwe ndi zosakaniza zace.

Pamene akhomere ndi ozizira rubberizing labala chili padziko zitsulo ndi zomatira ndi. Pankhaniyi, ife ntchito kumatira wapadera kuti ntchito osati umakaniko komanso mankhwala.

Tiyenera kusamalira kwambiri njira gumming odzigudubuza - extrusion. Njira imeneyi zimathandiza kuti apange wapamwamba kwambiri Kuphunzira ndipo amapereka kuwonjezeka kwambiri moyo utumiki wa migodi ya. Pamene tikugwira ntchito njira imeneyi amagwiritsidwanso ntchito kokha apamwamba mphira kusakaniza.

Njira gumming zida ndi miyeso lalikulu zojambula, akupangidwa ku malo unsembe.
