Intshayelelo kunye nezicelo zePhenol
I-Phenol, njengento ebalulekileyo ye-organic compound, idlala indima ephambili kumashishini amaninzi ngenxa yeempawu zayo ezizodwa kunye neekhemikhali. Isetyenziswa kakhulu kwimveliso yepolymer izinto ezifana phenolic resins, epoxy resins, kunye polycarbonates, kwaye iyinto ebalulekileyo ekrwada kumashishini amayeza kunye ne-pesticides. Ngokukhawuleza kwenkqubo yokwenziwa kwemizi-mveliso yehlabathi, imfuno ye-phenol iyaqhubeka nokukhula, ibe yinto ekugxilwe kuyo kwintengiso yeekhemikhali zehlabathi.
Uhlalutyo lwe-Global Phenol Production Scale
Kwiminyaka yakutshanje, imveliso ye-phenol yehlabathi ikhule ngokuthe ngcembe, ngomthamo oqikelelwayo wonyaka wokuvelisa ngaphezulu kwe-3 yezigidi zeetoni. Ummandla wase-Asiya, ngakumbi i-China, ngowona mmandla mkhulu wemveliso ye-phenol ehlabathini, ubalelwa ngaphezulu kwe-50% yesabelo semarike. Isiseko esikhulu sokwenziwa kwemveliso yaseTshayina kunye nophuhliso olukhawulezayo loshishino lweekhemikhali luqhubele phambili ukwanda kwemveliso yephenol. I-United States neYurophu nazo ziyimimandla emikhulu yemveliso, inegalelo elimalunga ne-20% kunye ne-15% yemveliso ngokulandelelanayo. Amandla okuvelisa eIndiya kunye noMzantsi Korea nawo akhula rhoqo.
Izinto zokuqhuba iMarike
Ukukhula kwemfuno ye-phenol kwimarike ikakhulu kuqhutywa ngamashishini aphambili aliqela. Uphuhliso olukhawulezayo loshishino lweemoto luye lwandisa imfuno yeeplastiki eziphezulu zokusebenza kunye nezixhobo ezidibeneyo, ukukhuthaza ukusetyenziswa kwe-phenol derivatives. Uphuhliso lolwakhiwo kunye nemizi-mveliso ye-elektroniki nayo inyuse kakhulu imfuno yee-epoxy resins kunye ne-phenolic resins. Ukuqiniswa kwemithetho yokhuseleko lwendalo esingqongileyo kuye kwabangela ukuba amashishini amkele ubugcisa bokuvelisa obusebenzayo. Nangona oku kunyuse iindleko zemveliso, kukwakhuthaze ukuphuculwa kobume boshishino.
Abavelisi abakhulu
Imakethi yehlabathi ye-phenol ilawulwa ikakhulu zizigebenga ezinkulu zemichiza, kubandakanya i-BASF SE evela eJamani, iTotalEnergies evela eFransi, iLyondellBasell yaseSwitzerland, iDow Chemical Company yaseUnited States, kunye neShandong Jindian Chemical Co., Ltd. evela eTshayina. I-BASF SE lelona lizwe livelisa i-phenol elikhulu, elinomthamo wonyaka wemveliso ongaphezu kweetoni ezingama-500,000, ebalelwa kuma-25% esabelo semarike yehlabathi. I-TotalEnergies kunye ne-LyondellBasell zilandela ngokusondeleyo, kunye nemveliso yonyaka ye-400,000 yeetoni kunye ne-350,000 yeetoni ngokulandelelanayo. I-Dow Chemical idume ngobuchwephesha bayo bemveliso obusebenzayo, ngelixa amashishini aseTshayina anenzuzo enkulu malunga nomthamo wemveliso kunye nolawulo lweendleko.
Ikamva elizayo
Kule minyaka imbalwa izayo, imarike ye-phenol yehlabathi kulindeleke ukuba ikhule nge-avareji yonyaka we-3-4%, ikakhulu ixhamla ekukhawulezisweni kwenkqubo yoshishino kuqoqosho olusakhulayo. Imimiselo yokukhusela indalo kunye nenkqubela phambili yezobuchwepheshe iya kuqhubeka nokuchaphazela ipateni yokuvelisa, kwaye ukuthandwa kweenkqubo ezisebenzayo zokuvelisa kuya kwandisa ukukhuphisana koshishino. Ukwahlukahlukana kweemfuno zentengiso kuya kuqhuba amashishini ukuba aphuhlise iimveliso ezilungele ukusingqongileyo ukuhlangabezana neemfuno zamashishini ahlukeneyo.
Umlinganiselo wemveliso ye-phenol yehlabathi kunye nabavelisi abakhulu bajongene namathuba amatsha kunye nemingeni. Ngokukhula kwemfuno yemarike kunye nemithetho engqongqo yokhuseleko lokusingqongileyo, amashishini kufuneka aqhubeke nokuvelisa izinto ezintsha kunye nokwandisa itekhnoloji yemveliso. Ukuqonda isikali semveliso ye-phenol yehlabathi kunye nabavelisi abakhulu luncedo ekubambeni ngcono iintsingiselo zeshishini kunye nokubamba amathuba entengiso.
