Mhedzisiro ye vulcanization pachimiro uye hunhu hwerabha

Mhedzisiro ye vulcanization pachimiro uye hunhu:

Mukugadzirwa kwezvinhu zverabha, vulcanization ndiyo danho rekupedzisira rekugadzirisa. Mukuita uku, rabha inosangana nemaitiro akasiyana-siyana emakemikari akaomarara, ichichinja kubva pachimiro chakarongeka kuenda pachimiro chakaita semuviri, ichirasikirwa nepurasitiki yerabha yakasanganiswa uye iine kusimba kwakanyanya kwerabha yakabatana, nokudaro ichiwana hunhu hwakanaka hwemuviri nehwemakanika, kuramba kupisa. Kushanda, kuramba solvent uye kuramba ngura zvinovandudza kukosha kwekushandiswa uye huwandu hwekushandiswa kwezvinhu zverabha.

Pamberi pe vulcanization: chimiro chakarongeka, kudyidzana pakati pemamorekuru ne van der Waals force;

Hunhu: kupfava kukuru, kureba kwakanyanya, uye kunyunguduka;

Munguva ye vulcanization: molekyuru inotanga, uye makemikari anobatanidza anoitika;

Mushure mekuumbwa kwe vulcanization: chimiro che network, pakati pemolecular ne chemical bonds;

Maumbirwo:

(1) Chisungo chemakemikari;

(2) Nzvimbo yechisungo chinobatana;

(3) Mwero wekubatana kwezvikamu;

(4) Kubatanidza zvinhu zvakasiyana-siyana;

Zvivakwa:

(1) Hunhu hwemakanika (simba rekureruka nguva dzose. Kuoma. Simba rekukwesha. Kureba. Kusununguka);

(2) Hunhu hwemuviri

(3) Kugadzikana kwemakemikari mushure mekuumbwa kwesimbi;

Kuchinja kwehunhu hwerabha:

Kutora rabha yechisikigo semuenzaniso, nekuwedzera kwedanho re vulcanization;

(1) Kuchinja kwehunhu hwemakanika (kupfava. Simba rekubvarura. Simba rekureruka. Simba rekubvarura. Kuoma) kuwedzera (kureba. Kumanikidzwa. Kugadzirwa kwekupisa kuneta) kudzikira

(2) Kuchinja kwehunhu hwemuviri, kuyerera kwemhepo uye kuyerera kwemvura kunoderera, hazvigone kunyungudika, zvinongozvimba chete, zvinovandudza kusimba kwekupisa

(3) Kuchinja kwekugadzikana kwemakemikari

Kuwedzera kugadzikana kwemakemikari, zvikonzero

a. Kubatana kwemakemikari kunoita kuti mapoka kana maatomu anoshanda nemakemikari asavapo, zvichiita kuti zviomere kukwegura kuenderere mberi.

b. Maumbirwo enetwork anodzivisa kupararira kwemamorekuru mashoma, zvichiita kuti zviomere kuti rabha ipararire

Kusarudzwa uye Kusarudzwa kweMamiriro eRubber Vulcanization

1. Kumanikidzwa kweVulcanization

(1) Kumanikidzwa kunofanira kushandiswa kana zvigadzirwa zverabha zvagadzirwa. Chinangwa ndeche:

a. Dzivirira rabha kuti isaburitse mabhuru uye wedzera kusimba kwerabha;

b. Ita kuti zvinhu zverabha zvifambe zvakanaka uye zadza chiumbwa kuti ugadzire zvigadzirwa nemapatani akajeka

c. Kuvandudza kubatana pakati pechikamu chimwe nechimwe (chikamu chinonamira nechikamu chejira kana chikamu chesimbi, chikamu chejira nechikamu chejira) muchigadzirwa, uye kuvandudza hunhu hwemuviri (senge kuramba kuchinjika) hwevulcanizate.

(2) Kazhinji, kusarudzwa kwekumanikidzwa kwe vulcanization kunofanirwa kusarudzwa zvichienderana nerudzi rwechigadzirwa, fomura, plasticity nezvimwe zvinhu.

(3) Muchokwadi, mitemo inotevera inofanira kutevedzerwa: purasitiki yakakura, kumanikidzwa kunofanira kuva kudiki; ukobvu hwechigadzirwa, huwandu hwezvikamu, uye chimiro chakaomarara chinofanira kunge chakakura; kumanikidzwa kwezvigadzirwa zvitete kunofanira kunge kudiki, uye kunyange kumanikidzwa kwakajairika kunogona kushandiswa.

Kune nzira dzakasiyana-siyana dzekushandisa vulcanization uye pressurization:

(1) Pombi ye hydraulic inoendesa kumanikidzwa kuenda kuchiumbwa kuburikidza neflat vulcanizer, uye yobva yaendesa kumanikidzwa kuenda ku rabha kubva muchiumbwa.

(2) Inomanikidzwa zvakananga nechinhu chinosvibisa simba (senge utsi)

(3) Kumanikidzwa nemhepo yakamanikidzwa

(4) Jekiseni nemuchina wejekiseni

2. Kupisa kweVulcanization uye nguva yekurapa

Kupisa kwe vulcanization ndiyo inonyanya kukosha pakuita kwe vulcanization. Kupisa kwe vulcanization kunogona kukanganisa zvakananga kumhanya kwe vulcanization, mhando yechigadzirwa uye mabhenefiti ehupfumi ebhizinesi. Kupisa kwe vulcanization kwakakwira, kumhanya kwe vulcanization kunokurumidza, uye kushanda zvakanaka kwekugadzira kwakakwira; zvikasadaro, kushanda zvakanaka kwekugadzira kwakaderera.

Kuwedzera tembiricha ye vulcanization kunogona kukonzera matambudziko anotevera;

(1) Zvinokonzera kutsemuka kwecheni yemamorekuru erabha uye kudzoka kwevulcanization, zvichikonzera kudzikira kwehunhu hwemuchina werabha.

(2) Kuderedza simba remachira muzvigadzirwa zverabha

(3) Nguva yekupiswa kwerabha inopfupikiswa, nguva yekuzadza inoderedzwa, uye chigadzirwa chacho hachina guruu.

(4) Nekuti zvigadzirwa zvakakora zvinowedzera musiyano wekupisa pakati pemukati nekunze kwechigadzirwa, zvichikonzera kusaenzana kwe vulcanization
