Txij li thaum Asmeskas thiab cov neeg Ixayees tau pib ua tub rog tawm tsam Iran thaum lub Ob Hlis 2026, Strait of Hormuz, lub ntiaj teb tseem ceeb ntawm lub zog thiab cov kab ke tshuaj lom neeg, tau poob rau hauv kev kub ntxhov. Qhov kev tsis sib haum xeeb ntawm thaj chaw no tsis tsuas yog ua rau cov nqi roj thoob ntiaj teb tab sis kuj ncaj qha txiav tawm lossis txwv tsis pub cov khoom lag luam tseem ceeb rau cov ntaub ntawv ua npuas dej hauv Middle East, ua rau muaj kev cuam tshuam tus nqi tsis tau pom dua hauv Tuam Tshoj tus ntshuam- nyob ntawm kev lag luam. Txog thaum kawg ntawm lub Peb Hlis 2026, tag nrho - cov nqi sib txuas ntawm cov ntaub ntawv ua npuas ncauj hauv Suav teb tau nce mus rau qhov siab tshaj plaws nyob rau hauv ze li plaub xyoos. Raws li cov ntaub ntawv soj ntsuam kev lag luam, tsab xov xwm no qhia meej txog tus nqi tshwj xeeb nce ntawm ntau yam ntaub ntawv ua npuas ncauj txij li thaum muaj kev kub ntxhov thiab delves mus rau hauv lub hauv paus kev sib kis logic.
Kev Tshaj Tawm Tus Nqi Tshaj: Tus Nqi -Tsiv Nqe Cua daj cua dub.Longzhong Cov ntaub ntawv soj ntsuam cov ntaub ntawv qhia tau tias cov khoom lag luam polyether thiab cov khoom lag luam cuam tshuam tau ntsib cov nqi sib tw thoob plaws lub Peb Hlis. Amid kev sib cog lus los ntawm Middle East kev tsis sib haum xeeb, tag nrho cov npuasCov khoom siv cov khoom lag luam raug cuam tshuam, ua kom pom qhov txawv ntawm kev lag luam tus qauv uas "cov ntaub ntawv raw tau coj mus rau qhov kev sib tw, cov khoom nruab nrab ua raws li kev nplua, thiab tus nqi nce siab heev." Raws li lub Peb Hlis 30, soft foam POP (polymeric polyol) topped daim ntawv nrog ze li ntawm 43% kev loj hlob txhua hli, thaum mos npuas polyether pom 36% nce. Txawm tias nyuaj ua npuas ncauj polyether, uas tau sau tus nqi tsawg tshaj plaws, tseem ua tau zoo kawg li 29% nce. Tsis tas li ntawd, muaj feem xyuam nrog foaming additives thiab isocyanate cov khoom ua tau zoo, nrog TDI (toluene diisocyanate) nce 20.8% thiab polymeric MDI (methyl diphenyl isocyanate) nce 20%.
Tus nqi nce qib: Mos ua npuas ncauj series ua nrog cov nqi sib kis tau zoo
Kev ua lag luam kev ua lag luam ntawm cov ntaub ntawv tseem ceeb foaming thiab lawv cov khoom muaj feem xyuam yog ranked los ntawm kev nce piv los ntawm qhov siab tshaj mus rau qis tshaj raws li hauv qab no:
Thawj qhov chaw: Mos ua npuas ncauj POP (polymer polyol)
Nce: kwv yees li 43%
Cov ntaub ntawv zoo li no feem ntau yog siv rau kev tsim khoom siab -rebound sponge, uas yog siv dav hauv cov rooj zaum hauv tsheb, siab- rooj tog zaum kawg, thiab lwm yam. Tus nqi siab tshaj plaws yog feem ntau yog vim lawv cov txheej txheem ntau lawm thiab tsis tshua muaj kev vam khom rau cov khoom siv raw khoom.
Qhov thib ob: Mos ua npuas ncauj polyether
Nce: kwv yees li 36%
Raws li cov khoom siv tseem ceeb rau cov rooj tog muag muag thiab cov ris tsho padding, mos ua npuas ncauj polyether muaj cov lag luam loj tshaj plaws. Tawm tsam cov keeb kwm yav dhau los ntawm tus nqi tseem ceeb nce hauv propylene oxide, nws cov nqi xa tawm yog qhov ncaj qha thiab nrawm tshaj plaws.
Qhov thib peb: rigid foam polyether
Nce: kwv yees li 29%
Rigid polyether ua npuas ncauj feem ntau yog siv hauv cov khoom siv hauv tsev, lub tsev rwb thaiv tsev, thiab daim ntawv thov vaj huam sib luag cia txias. Txawm hais tias nws tus nqi nce nqi kuj me me hauv tsev neeg polyether, qhov nce txhua hli ntawm ze li 30% tseem tsis tshua muaj keeb kwm.
Qhov chaw thib plaub: propylene oxide
Nce: kwv yees li 30.6%
Raws li cov khoom siv tseem ceeb tshaj plaws rau polyether polyols (suav txog 60% -70% ntawm cov nqi tsim khoom), tus nqi nce siab ntawm propylene oxide tau ncaj qha rau cov nqi hauv cov ntaub ntawv ua npuas ncauj.
Qhov thib tsib: TDI (toluene diisocyanate) thiab polymerized MDI
Nce: 20% -20.8%
Ob pawg khoom no ua cov tshuaj tua kab mob tseem ceeb thiab cov neeg ua npuas ncauj rau kev tsim cov khoom zoo nkauj, cov nplaum, thiab cov ntaub ntawv ua npuas ncauj nruj. Txawm hais tias lawv cov nqi loj hlob me ntsis qis dua li cov polyether, lawv tseem nyob ntawm qib siab.
Hais txog cov ntaub ntawv silicone sponge, thaum cov ntaub ntawv polyether ua npuas ncauj tau ntsib tus nqi nce siab thoob plaws tag nrho cov khoom lag luam, foamed silicone thiab nws cov khoom siv hluav taws xob sab saum toj ntawm cov khoom siv silicon tseem poob rau cov nqi teeb meem tshwm sim los ntawm Middle East tsis sib haum xeeb. Tsis zoo li cov khoom lag luam polyether cuam tshuam ncaj qha los ntawm naphtha tus nqi hloov pauv, tus nqi nce hauv foamed silicone feem ntau qhia txog tus nqi xa mus rau hauv cov organic silicon kev lag luam saw. Kev nce nqi ntawm cov khoom siv raw khoom xws li hlau silicon, methanol, thiab DMC (dimethyl carbonate), ua ke nrog cov nqi hloov pauv los ntawm cov thawj coj hauv ntiaj teb organic silicon kev lag luam, tau sib sau ua lag luam tus nqi rau foamed silicone.
Nyob rau hauv cov nqe lus ntawm tus nqi tshwj xeeb nce, tus nqi hikes rau foamed silicone thiab cov khoom siv silicone muaj cov qauv sib txawv. Kev soj ntsuam kev lag luam cov ntaub ntawv qhia tau hais tias txij li lub Peb Hlis 2026, cov khoom lag luam hauv qab ntawm silicone suav nrog 107 silicone roj hmab, roj hmab nyoos, roj hmab sib xyaw, thiab cov roj silicone feem ntau ua raws li tus nqi nce ntawm 200-300 yuan ib tuj. Nyob rau hauv lub foamed silicone tiav cov khoom lag luam, cov tuam txhab loj tau siv ntau qhov kev hloov kho tus nqi: Ntiaj teb no silicone tus thawj coj WACKER tshaj tawm tus nqi hikes rau nws cov khoom siv silicon-raws li lub Plaub Hlis 1, hais txog kev nce ntxiv hauv lub zog, cov khoom siv raw, thiab cov nqi thauj khoom vim yog Middle East tsis sib haum xeeb. Dow Chemical's Consumer Solutions Division tau ceeb toom rau Tuam Tshoj cov neeg koom tes nyob rau lub Peb Hlis 3 txog kev hloov pauv tus nqi tshiab pib lub Peb Hlis 27, nrog kev cia siab tias yuav nce li ntawm 5% mus rau 15%. Hauv tsev, Guangdong Jusi New Material Technology Co., Ltd. tau tsa tus nqi rau cov khoom lag luam qis los ntawm 8% -15% pib lub Peb Hlis 9; Orient Yuhong Adhesive Co., Ltd. nce nqi rau tag nrho cov khoom siv roj hmab foamed los ntawm 3%-5% pib lub Peb Hlis 6; thaum Shandong Luyuan Adhesives Co., Ltd. tau siv cov nqi hloov kho ntawm 5% -8% rau silicone nplaum thiab MS adhesives.
Txawm li cas los xij, vim muaj kev koom tes sib sib zog nqus ntawm Sanpu Company thiab cov tuam txhab raw khoom, tus nqi ntawm nws cov roj hmab silicone ua npuas ncauj tsis tau nce tam sim no. Yog tias koj xav tau silicone daim txhuam cev roj hmab, thov hu rau peb kom tau txais cov qauv dawb thiab cov lus hais tam sim no!
