ソリューションアプローチ
RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Application Workflow
1
Application & Agronomic Review
Define the use (crop input, adjuvant, soil amendment, post-harvest) and the agronomic, regulatory, and tank-mix requirements.
2
Input & Grade Selection
Match the surfactant or adjuvant, nutrient source, chelate, or formulation aid to the active, water quality, and label.
3
Compatibility & Rate Trial
Confirm tank-mix compatibility, dose, and stability, and size packaging (jugs, drums, totes, bulk) to the season and logistics.
4
Field Validation
Validate efficacy and crop safety in field trials, and lock the spec and supply plan for the season.
Recommended Chemistries (5)
Hydroxyethylidene Diphosphonic Acid
CAS 2809-21-4
リン酸エステル・誘導体
Antiscalant
Phosphonate adsorbs onto incipient CaCO3 crystal faces at sub-stoichiometric dose (threshold effect), distorting growth so scale can't nucleate on emitters
融点:198-199 沸点:578.8 Solubility: 1.15e+01 g/L

Amino Trimethylene Phosphonic Acid
CAS 6419-19-8
リン酸エステル・誘導体
キレート化 / 金属イオン封鎖
Sequesters Ca2+ and inhibits carbonate crystal growth; also stabilizes iron to prevent oxide plugging
融点:210 - 215 °C Solubility: 1000 mg/mL at 25 °C Vapor Pressure: 0.0000001

Polyacrylic Acid Sodium (PAAS)
CAS 9003-04-7
ポリマー・樹脂
コンディショニング
Low-MW polyacrylate disperses scale microcrystals and hardness fines so they pass through emitters instead of depositing

Phosphoric acid
CAS 7664-38-2
酸・塩類
pH adjuster
1805 (Phosphoric acid, solution) · Class Continuous low-dose acid injection holds pH below the carbonate saturation point, dissolving and preventing CaCO3 scale
融点:42 °C 沸点:> 130 °C at 760 mmHg 密度:1.892 at 25 °C

Citric Acid
CAS 77-92-9
酸・塩類
pH adjuster
Genuine fit. Citric-acid injection is a standard drip/fertigation practice for this exact problem: it lowers water pH to hold bicarbonates/carbonates in solution (preventing CaCO3 precipitation at emitters) and chelates dissolved iron to stop iron-oxide plugging. Used for both preventive dosing and emitter/drip-tape cleaning, and preferred where growers want an organic acid over mineral acids.
