Twayini polypropylene: ntchito, ubwino

Twayini polypropylene makamaka kufunika mu msika wa zipangizo ma CD. Kodi mankhwala ndipo kodi ntchito? Tiyeni yesetsani kuthetsa nkhani imeneyi.

Twayini polypropylene - ndichiyani?

Izi zili filament polypropylene, luso, filimu. Linapangidwa ndi torsion. Polypropylene twayini ndi chilonda pa spool popanda malaya wapadera.

Polypropylene zakuthupi wa gulu la polyolefins. Ndi wochezeka, otetezeka kwathunthu kwa anthu thanzi ndi chilengedwe. Choncho, polypropylene twayini ndipo alibe vuto. Kodi zikhale?

Kupanga polypropylene twayini

ndondomeko izi zikuchitika mu magawo angapo:

1. The hopper kusonkhanitsa umaperekedwa zipangizo - polypropylene.
2. Ku dipatimenti iyi yomalizidwa granulate akulowa kuyanika chipinda. kutentha ndi Lamulo pakati pa 60 ndi 110 madigiri Celsius.
3. Ndiye zopangira akubwerera mu thanki yosungirako, etc. - mu extruder ndi.
4. Apa, polima isungunuke, osasankhidwa, kenako kudyetsedwa kwa mutu pachilengedwe cha extruder lapansi.
5. Mu mawonekedwe a filimu ukonde chuma akudyetsedwa ndi ng'oma kuzirala. Kumene solidifies.
6. Ndiye filimu Kadulidwa mu maliboni.
7. Komanso anatambasula ndondomeko ikuchitika mu chipinda n'kulembekalembeka lathu. Izi zimachitika chifukwa cha kusiyana kwa imathamanga loyamba ndi lachiwiri pa sing'anga semivaltsev mpweya wokwanira otentha (mu lathu kutentha chipinda ndi osachepera 150 pa 210 madigiri kwambiri Celsius).
8. tepi ndipamene kanema fibrillyatore filament mphasa dongosolo. kenako chilonda kumtunda spools.

mankhwala Phunziro pankhaniyi

Twayini polypropylene chimagwiritsidwa ntchito m'mafakitale zotsatirazi:

• zaulimi;
• nyama malonda processing;
• kwa kupanga zingwe ndi diameters osiyana;
• kwa ma CD zolinga banja.

Mu ena mafakitale ntchito katundu pamwamba ubwino luso. Izi ma CD ulusi alimi amakonda kumanga udzu bales. Akatswiri kuona kuti munthu amene ntchito polypropylene twayini, nkomwe nthawi umabwerera kwa sisal.

Ubwino mankhwala

Twayini polypropylene amakhala ndi zinthu zotsatirazi:

• Zonyamula alkalis ndi zidulo;
• Iwo ali kwambiri katundu matenthedwe kutchinjiriza;
• mosasonkhezeredwa feteleza organic;
• mokwanira ndalama chuma;
• otetezedwa kwathunthu ndi wochezeka;
• kuonjezera zokolola;
• otetezeka ntchito (mwachitsanzo, zitsulo kapena kanasonkhezereka waya ingawononge dzanja anthu);
• kwambiri kumachepetsa mtengo wa ma CD.

Komanso, ma CD chuma umamumvera kuwola ndipo ali mkulu fibrillation. Ndi yabwino ntchito. Ngakhale ngati akatswiri onani, izi polypropylene ulusi ali drawback wina. Akuwonongedwa ndi dzuwa. Koma chikoka zimenezi ayenera mosalekeza. Komabe, ngati kupanga za ma CD chuma cha zigawo zikuluzikulu pamwamba yeniyeni kuwonjezera kwa kapangidwe kake, zimene zimawonjezera durability ndi kuwala fastness, vutoli likuchotsedwa.

Ubwino wina wa thonje polypropylene ndi mkulu buoyancy ake. izo ndi kugonjetsedwa ndi flexing ndi kumva kuwawa. Ndi insulator kwambiri, ndi yabwino kwambiri pamene inu zingwe ndi chepetsa.

Twayini polypropylene, zomwe zinabweretsa 60% zosakwana mtengo wa ulusi zachitsulo, malingana ndi mtundu zikhoza kugulidwa kwa 105-300 rubles. pa kilogalamu.

Izi zili kwambiri ma CD chuma. Kwambiri luso makhalidwe a thonje polypropylene amathandiza kuti kufunika kwambiri izo.
