1. Cov xwm txheej tam sim no thiab cov qauv ntawm cov nqi khoom siv raw hloov pauv
Raws li cov khoom siv lim dej tseem ceeb raucov lim dej, cov iav fiber tau pom ntau qhov kev nce nqi hauv xyoo 2025. Tus nqi ntawm cov xov hluav taws xob tau nce 19.8% - 22.22% xyoo-rau-xyoo, nrog rau cov lus hais tseem ceeb ncav cuag 8,800 - 9,200 yuan ib tuj. Tus nqi ntawm cov ntaub hluav taws xob tau nce 15.15% - 22.8%, feem ntau yog tsav los ntawm qhov kev thov los ntawm cov teb xws li 5G chaw nres tsheb hauv paus thiab cov tsheb fais fab tshiab. Cov tuam txhab ua lag luam hauv Suav teb tau muab nqi zog los ntawm kev txhim kho thev naus laus zis, thiab kev lag luam CR5 concentration tau mus txog 74%, ntxiv dag zog rau lub zog sib tham. Cov iav fiber suav txog li 30% - 40% ntawm cov nqi khoom siv lim, thiab nws cov nqi nce yuav ncaj qha tsav tsheb cov nqi tsim khoom lim, tshwj xeeb tshaj yog muaj kev cuam tshuam loj rau cov roj thiab roj sib cais lim dej ua haujlwm siab.
2. Cov nqi khoom siv raw thiab cov txheej txheem kis tau
Cov yam ntxwv ntawm cov qauv nqi lim
Cov lim cua compressor feem ntau muaj peb ntu tseem ceeb: lub thav duab hlau, cov khoom siv lim (iav fiber/txuj ci), thiab cov foob. Raws li cov ntaub ntawv kev lag luam, cov khoom siv raw suav txog li 60% - 70% ntawm tag nrho cov nqi, ntawm cov iav fiber muaj feem pua siab tshaj plaws (35% - 45%), ua raws li hlau (15% - 20%), thiab cov khoom siv pabcuam xws li roj hmab/yas suav txog 10% - 15%. Cov qauv no ua rau qhov cuam tshuam ntawm cov iav fiber hloov pauv ntawm tag nrho cov nqi ncav cuag 0.4 - 0.5, uas yog, nce 10% ntawm cov iav fiber yuav ua rau nce 4% - 5% ntawm cov nqi lim. Thaum qhov cuam tshuam ntawm tus nqi txo qis ntawm cov hlau yog qhov txwv (qhov cuam tshuam coefficient yog li 0.15) vim tias nws feem ntau siv rau cov khoom tsis yog lub hauv paus hauv cov lim.
Lub sijhawm qeeb thiab elasticity ntawm kev sib kis nqi
Cov tuam txhab tsim cov lim dej feem ntau siv tus qauv nqi txhua peb lub hlis, thiab nws yuav siv sijhawm 1 - 2 lub hlis rau cov khoom siv raw nce nqi kom xa mus rau tus nqi muag kawg. Tom qab tus nqi iav fiber nce siab hauv Q2 2025, qee cov chaw tsim khoom tau tiv thaiv kev nyuaj siab los ntawm kev txo cov luv nqi tshaj tawm (hloov chaw nce nqi ncaj qha), ua rau 2 - 3 feem pua ntawm cov nyiaj tau los tag nrho poob qis. Cov neeg siv khoom qis dua qhov kev nkag siab ntawm tus nqi qhia txog kev sib txawv: cov neeg siv khoom lag luam (xws li cov tuam txhab petrochemical) muaj kev lees txais ntau dua vim tias cov lim dej suav nrog tsawg dua 5% ntawm cov nqi ua haujlwm thiab kev saib xyuas khoom siv; thaum cov chaw tsim khoom me me thiab nruab nrab cua compressor yuav tig mus rau cov khoom siv hloov pauv pheej yig, ua rau kev sib tw ua lag luam nce ntxiv.
3. Cov tswv yim daws teeb meem ntawm cov lag luam thiab kev hloov kho kom haum rau kev lag luam
Kev tswj hwm cov khoom siv dynamic
Cov lag luam loj loj tiv thaiv kev pheej hmoo los ntawm "kev yuav khoom ob qhov chaw": yuav hlau hauv tebchaws kom tau txais txiaj ntsig los ntawm tus nqi qis, thiab tib lub sijhawm kos npe rau cov ntawv cog lus ntev nrog cov tuam txhab tsim khoom siv iav fiber hauv Thaib kom kaw 70% ntawm qhov kev thov. Cov lag luam me thiab nruab nrab siv txoj kev "tsis txhob yuav khoom ntau dhau", khaws cov khoom muag 3 - 6 lub hlis thaum tus nqi iav fiber qis, tab sis lawv yuav tsum tau them tus nqi ntawm 1.5% - 2% nce ntxiv ntawm cov nqi khaws khoom.
Kev hloov pauv thev naus laus zis thiab kev tsim kho tshiab ntawm cov txheej txheem
Muaj ib txhia chaw tsim khoom tau tsim cov khoom siv lim dej sib xyaw los hloov cov iav fiber ntshiab, txo cov iav fiber siv rau ib lub lim dej los ntawm 20% - 30%. Ntawm sab kev tsim khoom, kev siv tshuab laser txiav + automated winding tau txhawb nqa, txo cov hlau seem ntawm 8% mus rau 3%, ib feem them rau qhov cuam tshuam ntawm cov khoom siv raw hloov pauv.
