Kuonekwa kwesarufa nhemaikristaro yakasviba yakasviba, uye pamusoro pekristaro ine madhigirii akasiyana echiedza (kuchinja nekuchinja kwesimba).Mushonga wemvura imvura nhema, uye nhema yesarufa inoda kunyungudutswa nesodium sulfide solution.
Iyo pro Sulfur dema crystal idhayi yekugadzira iyo ndeyemhuri yesarufa dhayi.Inowanzoshandiswa muindasitiri yemachira kudhaya machira edonje sezvo ichipa yakadzika dema ruvara.Sulfide Black Crystal inozivikanwa nekukasira kwayo kwemavara, zvinoreva kuti haizopedziki kunyangwe mushure mekugezwa kakawanda kana kuvhenekwa nezuva.Iyo zvakare inodhura-inoshanda uye inowanikwa zvakanyanya mumusika.
2,4-dinitrochlorobenzene dhizaini, iyo inogadzirwa ne 2,4-dinitrochlorobenzene pasi pemamiriro e alkaline kuti iwane 2,4-dinitrophenol sodium munyu, iyo inozowedzerwa kune sodium polysulfide mhinduro ye vulcanization.Mushure me oxidation, kusefa, Chigadzirwa chakapedzwa chakaomeswa.
Sulfur dema inonyanya kushandiswa kudhaya donje, hemp, viscose nemachira ayo akasanganiswa.Mazhinji machira edenim (matema) anozivikanwa kumba nekune dzimwe nyika akagadzirwa neshinda nhema yakarukwa neshinda chena.Sulfur dema ine akawanda disulfide zvisungo mushure mekuderedzwa ne sodium sulfide, uye zviri nyore kuve oxidized kuderedza kusimba kwemachira akadhayiwa, ndiko kuti, brittleness.Kuti udzivise brittle kukuvara, unofanirwa kuterera kune aya mapoinzi:
1, Dzora huwandu hwesarufa nhema.Kunyanya kuwanda kwesarufa dema, kunowedzera kukanganisa kunoitika.
2, Geza zvakakwana kuti uderedze ruvara runoyangarara pane inotakura.
3、Shandisa Taikoo Oiri yekuwedzera kudzivirira kuputika.
4、Kukwesha nemvura yakachena usati wadhaya.Shinda yakasanganiswa nemvura yebvunzo mushure mekudhayiwa ine mwero uri nani weembrittlement kupfuura lye.
5, Pukuta nenguva mushure mekudhaya kuti uderedze zvirimo zve-anti-brittle aids zvinokonzerwa nekuwanda kwemvura.
