Tilmaamaha habdhaqanka soo jiidashada (EN 15426: 2018)

Si loo qiimeeyo hab-dhaqanka soo jiidashada shumacyada gubanaya iyadoo la cabbirayo miisaanka saafiga ah ee shumaca iyo tusmada danbaska ee wakhti go’an heerkulka qolka 20℃ ± 5℃.

Dhammaan imtixaanada waxay ku saleysan yihiin heerarka EU: (EN 1593: 2007) (EN 15426: 2018).

Qingdao Yuan Bridge Houseware Co., Ltd 

Caadiyan waxaa jira waxyaabo lagu daro oo ku jira shumaca gudaheeda .
Tusaale ahaan, shumac ur udgoon oo ka samaysan paraffin ayaa ku dari doona qadar yar oo ah wax yar oo microcrystalline ah: waxay ka dhigi doontaa shumaca jilicsan oo ka caawin doonta in laga saaro suufka suufka ah ee la soo saaro inta lagu jiro habka qaboojinta ee paraffin, si paraffin uusan u kicin si xad dhaaf ah.
Ku dar qadar yar oo shamac ah (laga soo saaray caanaha xoolaha): Waxay ka caawisaa dareeraha dhukayga iyo saliidda lagama maarmaanka ah inay isku darsamaan inta lagu jiro habka wax soo saarka, taas oo ka dhigaysa xuubka dhuka si sahlan in loo qaabeeyo, ka caawinta dhuxusha in ay ka baxdo gidaarka muraayadda. muuqaalkuna wuu fiicnaanayaa. Laakiin midabku waa huruud.
Stearic acid (khudradda ama saliidda xoolaha laga soosaaray): waxaa lagu daraa si ay u caawiso kordhinta adkaanta iyo cadaanka shumaca, maaskaro midabka saliidda lagama maarmaanka ah, nafiso qiiqa madow ee gubasho saafi ah, oo ka dhigaysa shumaca mid adag.
Midabka saliidda leh: Shumac midab leh.

Si kastaba ha ahaatee, dhammaan waxyaabaha lagu daro isku mar lama isticmaali karo.

Tusaale ahaan, isticmaalka isku mar ah ee stearic acid iyo shamac gaasku waxay keeni doontaa fal-celin kiimikaad, taas oo ka dhigi doonta dusha sare ee shumacyada.
Stearic acid waxay u shaqeysaa ka soo horjeeda wax microcrystalline ah, iyo isku darka isku mar ah waxay ka dhigan tahay in adkaanta shumaca aan la bedelin.
Aashitada stearic-ka ee xad-dhaafka ah ayaa si dhakhso ah u midabayn doonta lakabka dhuka.

Sidaa darteed, shumacyada naqshadaha kala duwan waxay isticmaalaan noocyo kala duwan iyo waxyaabaha ku jira waxyaabaha lagu daro.
Marka la eego goobta lagu hubinayo in muuqaalka shumaca uu nadiif yahay, tijaabada gubashada ayaa ah habka ugu badan ee tijaabada ah ee lagu tijaabiyo caanaha warshadda shumaca.
