Kwesinye isikhathi abasebenzisi bangacela kuphela ukuthi i-polcanzi eyenziwe nge-polcanized ingadonswa isikhathi esingakanani ngaphandle kokuphuka. Lokhu kungenye impahla ebalulekile yezinto ezibonakalayo ekuhlolweni kwengcindezi kwezimpawu ezijwayelekile ze-dumbbell njengoba kuchazwe yi-ASTM ne-ISO. Amaphrothokholi alandelayo angasiza amakamethi ahlangabezane nezidingo zabasebenzisi.

1. SBR

I-SBRELerized nge-Emulsion ku -10 ° C esikhundleni sika-50 ° C

2. NR

Phakathi kwamabanga ahlukahlukene we-NR, injoloba yezobusuku ye-CV60 ye-CV60 ine-elongation ephakeme kakhulu.

3. Neoprene nabaphangi

Ezakhiweni ze-neoprene, ama-inorganic filler anosayizi omkhulu wezinhlayiyana kunokuba usayizi omncane wezinhlayiyana kufanele asetshenziselwe ukuthuthukisa ukugcwala kwekhefu eliseduze. Ngaphezu kwalokho, esikhundleni sekhabhoni eliqinisiwe noma eliqinisiwe elihlanganisiwe nge-carbon emnyama eshisayo ingathuthukisa ukugcwala kwekhefu eliseduze.

4. TPE ne-TPV

Ama-elastomers we-thermoplastic ne-Thermoplastic Alvucanizates avame ukuba yi-asotropic, ikakhulukazi ama-elastomers abunjiwe abunjiwe ezindaweni eziphakeme kakhulu, lapho amandla ashubile kanye nokuqina kweziqukathi kuncike ekuqondisweni kokugeleza kwawo.

I-5. Carbon Black

Ukusetshenziswa kwekhabhoni emnyama ngendawo ephansi engaphezulu komhlaba nesakhiwo esiphansi kanye nenani lokugcwalisa elincishisiwe le-carbon emnyama lingathuthukisa ukugcwala okuthe xaxa kwesakhiwo.

6. I-talcum powder

Ukubuyisela inani elifanayo lekhabhoni elimnyama ngosayizi omncane wezinhlayiyana nge-talc kungathuthukisa ukugcwala okuthe xaxa kwe-compound, kepha kunomthelela omncane kumandla ashubile futhi kungakhulisa i-modulus ngohlobo oluphansi.

7. I-Sulfur Vulcanization

Inzuzo evelele yesibabule uma iqhathaniswa ne-peroxide Vulcanization ukuthi kungenza impahla yerabha ibe nokugcwala okuphezulu. Ngokuvamile, izinhlelo eziphakeme ze-sulcanization zingadlulisela ukugcwala okungcono okungcono ku-compound kunamasistimu we-sulfur vulcanization.

8. Ijeli

Izikhangiso zokwenziwa ezinjenge-SBR ngokuvamile ziqukethe ukuqina. Kodwa-ke, ukuxubana ama-compounds emazingeni okushisa angenhla kwe-163 ° C kungakhiqiza ama-gels avulekile (angavulwa avulekile) nama-gels ahlanganisiwe (angenakugoqeka kuma-solvents athile). Womabili ama-gels anciphisa ukugcwala okuthe xaxa kwe-compound, ngakho-ke izinga lokuxuba lokuxuba le-SB kufanele liphathwe ngokucophelela.

9. Ukuxuba

Ukuhlanganisa kuthuthukisa ukuhlakazwa kwekhabhoni emnyama, okusiza ukuthuthukisa ukugcwala okuthe xaxa kwe-compound.

10. Imiphumela yesisindo se-molecular

Nge-ruble ye-NBR Raw, ukusetshenziswa kwendlela ephansi ye-money kanye nesisindo esiphansi samangqamuzana kungathuthukisa ukugcwala kwekhefu eliseduze. I-Emulsion SBR, i-SPRED SPR, BR ne-IR nayo ilungele lokhu.

11. degree of vulcanization

Ngokuvamile, izinga eliphansi le-Vulcanization lingaholela ekubunjweni okuphezulu kwe-compound.
