Shumaca waa aalad iftiin maalinle ah.Marka loo eego wakiilada kala duwan ee taageeraya gubashada, shumacyada waxaa loo qaybin karaa shumac nooca paraffin iyo shumacyada nooca paraffin.Shumacyada nooca paraffin waxay inta badan u isticmaalaan paraffin sida wakiilka kaalmeeya gubashada, halka shumacyada nooca paraffin ay isticmaalaan polyetylen glycol, Trimethyl Citrate iyo soybean wax sida wakiilka kaalmeeya gubashada.Intaa waxaa dheer, marka loo eego shuruudaha codsiga, shumacyadu waxay inta badan leeyihiin isticmaalka muhiimka ah ee muuqaalada gaarka ah sida xafladaha dhalashada, xafladaha diinta, baroorta wadajirka ah, dhacdooyinka arooska ee casaanka iyo caddaanka ah.

Marxaladda hore ee horumarinta, shumacyada ayaa inta badan loo isticmaali jiray iftiinka, laakiin hadda Shiinaha iyo xitaa dunidu waxay asal ahaan xaqiiqsadeen daboolka ballaaran ee nidaamyada nalalka korontada, iyo baahida shumacyada iftiinka ayaa si degdeg ah loo yareeyey.Waqtigan xaadirka ah, qabashada xafladaha diiniga ah waxaa lagu cunaa shumacyo aad u badan, laakiin tirada ilaahyada diiniga ah ee Shiinaha ayaa ah kuwo aad u yar, baahida shumacyaduna wali waa yar yihiin, halka baahida shumacyada dibadda ay aad u badan tahay.Sidaa darteed, tiro badan oo alaabta shumaca gudaha ah ayaa loo dhoofiyaa dibadda.

Marka loo eego warbixinta falanqaynta ee qaabka tartanka iyo tartamayaasha ugu waaweyn ee warshadaha shumaca Shiinaha laga bilaabo 2020 ilaa 2024, Shiinaha waa dhoofiye shumaca weyn.Gaar ahaan, marka loo eego xogta ku habboon ee uu sii daayay Maamulka Guud ee Kastamka Shiinaha, ee suuqa dhoofinta, mugga dhoofinta shumacyada kala duwan iyo alaabada la midka ah ee Shiinaha ayaa gaadhay 317500 tan sanadka 2019, koror ku dhow 4.2% sannadkii hore;Qiimaha dhoofinta ayaa gaaray 696 milyan oo doolarka Mareykanka ah, koror ku dhow 2.2% sanadkii hore.Suuqa soo dejinta, mugga soo dejinta ee shumacyada kala duwan iyo alaabada la midka ah ee Shiinaha ayaa gaadhay 1400 tan sanadka 2019, hoos u dhac 4000 oo tan ah marka loo eego sanadkii hore;Mugga soo dejinta ayaa gaadhay US $13 milyan, taasoo la mid ah tii sannadkii hore.Waxaa la arki karaa in dhoofinta shumaca Shiinaha ay door muhiim ah ku leedahay suuqa caalamiga ah.

Waqtigan xaadirka ah, shumacyada fudud ee fudud ma dabooli karaan baahida dadka deggan Shiinaha dhammaan dhinacyada.Tani waxay u baahan tahay soosaarayaasha shumaca gudaha inay si joogto ah u cusboonaysiiyaan tignoolajiyada wax soo saarka, horumariyaan alaabada shumaca-dhamaadka sare leh ee caafimaad qaba, badbaado leh iyo deegaanka saaxiibtinimo, iyo inay sii balaariyaan tartanka warshadaha ee suuqa.Waxaa ka mid ah, shumacyada udugga, sida qayb-hoosaadka alaabta shumaca, waxay si tartiib tartiib ah u muujiyeen horumar wanaagsan sannadihii la soo dhaafay.

Si ka duwan shumacyada dareenka dhaqameed, shumacyada udgoon waxaa ku jira saliidaha lagama maarmaanka ah ee dhirta dabiiciga ah.Marka ay gubaan, waxay soo saari karaan udgoon wanaagsan.Waxay leeyihiin saameyno badan sida quruxda iyo daryeelka caafimaadka, neerfayaasha qaboojiya, nadiifinta hawada iyo baabi'inta ur.Waa hab dhaqameed badan oo qolka lagu daro udgoon.Sanadihii la soo dhaafay, iyadoo ay ugu wacan tahay horumarinta joogtada ah ee heerka nolosha iyo isticmaalka dadka Shiinaha deggan iyo rabitaankooda nolol raaxo leh, shumacyada udgoon ayaa si tartiib tartiib ah u noqday xoog cusub oo loogu talagalay horumarinta Suuqa shumaca ee Shiinaha.

Falanqeeyayaasha warshadaha ayaa sheegay in sannadihii ugu dambeeyay, iyada oo la hagaajinayo dhismaha kaabayaasha tamarta Shiinaha, baahida isticmaalka shumaca dhaqameed ee Shiinaha ayaa si degdeg ah hoos ugu dhacay, halka baahida isticmaalka dibadda ee shumacyadu ay aad u badan yihiin.Sidaa darteed, horumarinta suuqa dhoofinta shumaca Shiinaha ayaa sii socota inay fiicnaato.Waxaa ka mid ah, shumaca udugga ayaa si tartiib tartiib ah u noqday goob cusub oo isticmaalka suuqa shumaca Shiinaha oo leh waxtarkeeda wanaagsan.
