Ii. Material - Scene Adaptation: Precise Application Practice yeRubber Rollers
Zvinodiwa zvetembiricha, zvepakati, kudzvanywa, friction coefficient, nezvimwewo zverabha rollers mune akasiyana maindasitiri mamiriro anosiyana zvakanyanya. Iko kusarudzwa kwezvinhu kunoda kuwana mutsara chaiwo we "performance - kuda"
1. Indasitiri yekudhinda nekurongedza: Kutsvaga yunifomu yekuendesa ingi uye kupfeka-kusingachinjiki.
Zvishandiso zvinoenderana: Natural rubber (NR) rollers, nitrile rubber (NBR) rollers
Maitiro ekushandisa: Mukuita kudhinda, iyo yakakwira elasticity uye kusimba kwakanakisa kwemasikirwo erabha rollers anogona kuve nechokwadi cheyunifomu inki application, kudzivirira ingi mavara uye kupotsa kudhinda. Kune zviitiko apo inki zvinonyungudutsa zvinosangana, kupikisa kwemafuta e nitrile rubber rollers kunogona kudzivirira zvinhu kubva pakuzvimba nekuremara, kuve nechokwadi chekudhinda chaiko.
Mashandiro akajairika: Ink transfer rollers ye offset printing machines, pressure rollers ye gravure printing machines, uye laminating rollers ekurongedza mafirimu.
2. Indasitiri yekudhinda machira nekudhaya: Kuenzanisa kusamira kwetembiricha uye anti-zvinoda kusvibisa
Zvishandiso zvinoenderana: Silicone rabha (VMQ) rollers, chloroprene rubber (CR) rollers
Mafungiro ekushandisa: Padanho repamusoro-pakuseta tembiricha yekudhinda nekudhaya (tembiricha 150-200 digirii), kukwirisa-kupimbira kwesilicone rubber rollers kunogona kudzivirira kuchembera nekushanduka kwemafuta, uye kusabatika kwepasi kune fiber kunoderedza kupinda kweshinda. Iwo machira anotungamira machira emidziyo yekunze anogadzirwa neneoprene rabha, ine yakanakisa kuramba kwemamiriro ekunze kudzivirira kukukurwa kwemwaranzi yeultraviolet uye nharaunda dzine hunyoro, nekudaro vachiwedzera hupenyu hwavo hwesevhisi.
Mashandisirwo akajairika: Mucheka wekuisa muchina kudzvanya roller, dhayi uye yekupedzisa dhizaini giding roller, textile printing machine scraper roller.
3. Indasitiri yekugadzira simbi: Inoshingirira kumarara oiri uye-kumanikidzwa kwemamiriro ekushanda
Zvishandiso zvinoenderana: Nitrile rubber (NBR) rollers, fluorine rubber (FKM) rollers
Mashandisiro ekushandisa: Mukugadzira simbi inotonhora-yakakungurutswa marata nealuminium foil, ma roller erabha anofanirwa kusangana nemafuta ekucheka, emulsion nezvimwe nhepfenyuro. Kuramba kwemafuta kwenitrile rabha kunogona kudzivirira kuzvimba kwezvinhu, uye panguva imwe cheteyo, ine simba rakakwana rekushingirira-kukunguruka. Nezvepamusoro-zvemichina yekugadzira simbi inosangana nezvinotonhodza zvinotonhora, kusamira kwekemikari kwemafluororubber rollers kunoita kuti kushanda kwakadzikama munhau dzinotyisa.
Mashandisirwo akajairika: Mapumburu ekutsigira simbi inotonhora inotenderedza zvigayo, kumanikidza rolls yealuminium foil slitting muchina, uye dhizaini rolls yechaiyo yekudhinda midziyo.
4. Indasitiri yekugadzira chikafu: Sangana nekuchengetedza uye tembiricha yekudzivirira zvinodiwa
Inoenderana zvinhu: Silicone rabha (VMQ) roller
Maitiro ekushandisa: Mukuita senge mabhandi ekutakura chikafu, bhisikiiti calendering, uye chokoreti coating, iyo biocompatibility yesilicone rubber rollers inogona kudzivirira kusvibiswa kwechikafu. Kukwirisa kwadzo-kuramba tembiricha kwakakodzera-nzvimbo yetembiricha padanho rekugadzirisa (80-150 digirii), uye zviri nyore-kuchenesa nzvimbo inopindirana nemitemo yehutsanana hwechikafu.
Mashandisirwo akajairika: Madhindindi emabhandi ekutakura chikafu, ma roller emabhisikiti ekugadzira michina, ekutungamira ma roller emidziyo yekurongedza zvihwitsi.

Zvishandiso zvinoenderana: fluororubber (FKM) rollers, yakakosha silicone rubber rollers
Mafungiro ekushandisa: Muzviitiko zvakaita sekugadzirwa kwechikamu chemuchadenga uye kufambiswa kwemidziyo mumidziyo yemakemikari, ma roller efluororubber anoda kushingirira tembiricha yakanyanyisa (-50 madhigirii kusvika 250 madhigirii ) uye zvinosvibisa zvinosvibisa. Iko kugadzikana kwemakemikari uye yakakwirira-kupisa kupikisa kwefluororubber rollers inogona kusangana nezvinodiwa zvinodiwa. Mukugadzira semiconductor, mawafer ekuchinjisa rollers anogadzirwa neakakosha silicone rabha, ane kuchena kwepamusoro uye kuita kwekudzivirira kunogona kudzivirira kusvibiswa kwewafers.
Mashandisirwo akajairika: aviation component yekukuya ma roller emidziyo, kemikari inotakura rollers, semiconductor wafer transfer rollers.
Iii. Misimboti Yakakosha uye Mafambisirwo eNhungamiro yeKusarudza Material
Kusarudzwa kwerubha rollers kunofanira kutevera mitemo mikuru mitatu ye "kushanda kwemamiriro ekutanga, kushanda kwekuita, uye mari yekuenzanisa" : Kutanga, tsanangura zvakajeka mamiriro ekushanda emamiriro ezvinhu akadai sekushisa kwekushanda, kusangana kwepakati, uye mutoro wekumanikidza; Chechipiri, enzanisa tembiricha yekudzivirira renji, kuenderana kwekemikari uye michina yezvigadzirwa zvinoenderana nemaparamita. Chekupedzisira, pasi pechigadziro chekusangana nezvinodiwa zvekuita, zvese mutengo wezvinhu uye kugadzirisa kunofanirwa kuverengerwa.
Mune ramangwana, kugadzirwa kwerubha roller zvinhu kuchatarisisa nzira mbiri huru: imwe ikuvandudza kwezvakatipoteredza, kugadzira ma substrates anoparara erabha uye yakaderera-VOC additives kuderedza kukanganiswa kwezvakatipoteredza; Yechipiri ndeyekushanda musanganiswa. Kuburikidza nekugadzirisa kusanganisa (sekusanganisa nitrile rabha nepolyvinyl chloride) kana tekinoroji yekuisa pamusoro, kubatanidza kuita kwakawanda senge "wear resistance + oil resistance + tembiricha kuramba" kunogona kuwanikwa, zvichiwedzera kuwedzera miganhu yeapplication munzvimbo dzepamusoro{4} dzekupedzisira.
