Chii chekuita kana mhando yePVC inopupuma regulators isina kunaka?

Munguva yekupupuma kwezvinhu, gasi rakaora neanoita furo rinoumba mabubble mukunyunguduka. Pane maitiro emabhuru madiki arikukwira akananga kumabhuru mahombe mune aya mabhuru. Saizi uye huwandu hwemabhuru hahuna hukama chete nehuwandu hwekupupuma mumiririri wakawedzerwa, asiwo kune kusimba kwepolymer kunyungudika. Kana hukuru hwacho hwakanyanya kuderera, gasi rinogona kubuda nyore pakupararira kusvika pamusoro pekunyunguduka, uye mabhuru madiki anobatana pamwechete kugadzira mabhuru makuru. Iwo marefu mashetani emaketani eanopupa maregulator akabatikidzwa uye anonamatira kune molecular cheni dzePVC, achigadzira imwe network sisitimu. Kune rumwe rutivi, inokurudzira zvinhu zvepurasitiki, uye kune rumwe rutivi, inovandudza simba rePVC kunyunguduka, kuitira kuti furo sero rusvingo rikwanise kumira gasi mukati mefoam cell panguva yekuputira, kuitira kuti irege kuputika. nokuda kwesimba risina kukwana. Foam regulator inogona kuita kuti zvigadzirwa zvidiki uye zviwande, zvine yunifomu uye inonzwisisika pore chimiro, ichideredza zvakanyanya kuwanda kwemuviri wefuro. Hunhu husina kunaka kana kusakwana dosi yezvinodzora kupupa zvinogona kutungamira kusimba rakaderera refuro, zvichikonzera kuputika kana tambo mabhuru.

Huremu hwemamorekuru uye viscosity yeanopupa maregulator anogadzirwa nevagadziri vakasiyana anosiyana zvakanyanya. Kana zvigadzirwa zvinopupa zvichityora kana tambo mabhubhu, uye dzimwe nzira dzikasashanda, kutsiva iyo inopupa regi kana kuwedzera dosi nenzira kwayo kunogona kuburitsa zvakakosha. Nekudaro, kuwedzera kana kutsiva anopupa marongero ane epamusoro mamorekuru uremu anogona kuwedzera chigadzirwa density nekuda kwekunyanyisa viscosity, izvo zvinodzivirira kuwedzera kwemabhuru mukunyungudika. Uye nekuda kweiyo yakakwira viscosity yekunyunguduka, iyo fluidity ichadzikira, zvichikonzera kusaenzana kwekuyerera kwe mold, inokanganisa flatness yeplate pamusoro, uye kunyangwe ipfupi nguva yekugadzira, zvichiita kuti mold paste kutadza, kunyanya kana kugadzira mahwendefa ane ukobvu. kusvika pasi pe10mm.
